The Swedish brand Electrolux (Electrolux) produces not only vacuum cleaners, washing machines and so on household appliances. The products include climate control equipment, including ventilation units: supply and exhaust and supply.

Since installation of such devices can only be done by specialists, we will not describe it in detail. We will focus on an overview of the characteristics, capabilities and advantages.

General description: about types of installations

ventilation units Electrolux are divided into 2 types:

1. Star EPVS: supply and exhaust, with recovery and electric heater. The line includes 6 models of varying performance, the device and functions are the same.
2. Fresh Air EPFA: supply air, with electric heater. The line includes 3 models of different performance, the device and functions are the same.

In the review we will focus mainly on the first line - it is more popular and widespread.

U construction of models Electrolux Star EPVS

The body of the units is rectangular, made of galvanized steel sheet. Inside there is thermal and sound insulation made of polystyrene foam and foam rubber.

The housing contains:

• 2 fans (one for supply, the other for exhaust), with overheating protection and 2 speeds;
• 2 temperature sensors, one immediately at the inlet of street air, the second at the outlet of the influent from the installation (after the heater and recuperator, that is, you can know exactly how many degrees it is heated);
• 2 filters, on the supply and on the exhaust, type EU-5 (so as not only to prevent polluted air from entering the room, but also not to pollute the recuperator);
• plate recuperator.

There are two round pipes protruding from two opposite sides of the housing, to which the air duct lines are connected. One line carries fresh air from the street (supply), and the other draws air from the premises (exhaust). Inside, these lines cross, passing through the recuperator and “exchanging” heat.

On the sides of the body there are mounting brackets: 2 pieces each (4 in total). On the one hand, there is a service hatch: through it you can remove the filter and recuperator for cleaning.

Additionally, 1 more fan can be installed in the supply and/or exhaust line, models EPVS-EF - to increase the pressure. This will partially increase the amount of air passing through. For each EPVS model there is a separate corresponding fan model (characteristics are given below).

For control, the devices have a wall-mounted control panel with a screen. You can read more about the remote control below.

Purpose and scope

Any model from the EPVS line can be used in ventilation systems residential and non-residential buildings (used for all premises of the building). It could be:

• private house;
• shop;
• office;
• public establishment (cafe, restaurant, bar, etc.);
• swimming pool, gym;
• production premises.

About production premises- there is a limitation. The installations are not intended for the removal of explosive impurities, acid vapors, varnishes, or “heavy” suspensions.

Pros and cons

The advantages of the EPVS line include:

• separate places for air intake and exhaust;
• “hidden” installation;
• Can be used with an air duct system;
• possibility to install an electric heater (purchased separately);
• presence of a filter (and it can be cleaned);
• the presence of a timer with the ability to set several modes for different days/times;
• the presence of a remote control on which various readings are displayed.

Relatively high price This is not a disadvantage: recuperators of this series are more serious devices than “ordinary” ones household models(like UVRK or “Prana”).

A minor drawback is the lack of a remote control. remote control and electric heater as standard.

Control method: wall remote control

The installation is controlled from a wall-mounted plastic remote control (model - ERC-16), which is connected to the device via a cable. The remote control has a screen and 6 round mechanical buttons.

The screen is large, liquid crystal, with blue backlight. During operation, the following data is displayed on it:

1. Day of the week.
2. Current time.
3. Selected fan speed.
4. Supply air temperature (after the recuperator).

The remote control can also show the temperature at the entrance to the installation and the condition of the filter (signal that it is time to clean/change it).

Purpose of the buttons:

1. Turn on/off the remote control and installation.
2. Resetting the counter before cleaning/replacing the filter, viewing the air temperature at the installation inlet.
3. Setting the date/time, or exiting to the timer setting mode.
4. Switching fan speed.
5. Decrease the selected parameter by 1 unit, change modes (when setting the timer).
6. Increase the selected parameter by 1 unit, change modes (when setting the timer).

Characteristics and prices of the Star EPVS line (air handling units)

Included in the range of air handling units with recuperator includes 6 models. They are marked with numbers (EPVS line name + number) that indicate the approximate maximum air flow.

Additional fans are marked as EPVS-EF + number of the corresponding installation model (example: EPVS-EF 200).

List of models and approximate price for each installation and an additional fan for it:

1. EPVS 200: about 36,000 rubles(additional fan - about another 5,000 rubles).
2. EPVS 350: about 52,000 (6,500).
3. EPVS 450: approx. 61,000 (7,500).
4. EPVS 650: about 77,000 (9,000).
5. EPVS 1100: about 94,000 (10,500).
6. EPVS 1300: about 110,000 (13,000).

Here are the main characteristics of the installations Electrolux EPVS, as well as additional fans ( EPVS-EF, must be purchased separately):

Characteristics and prices of the Fresh Air EPFA line (air handling units)

In terms of device air supply units Fresh Air EPFA are different from the EPVS line. First of all, they only have 1 line for air, supply air. An electric heater is included as standard.

The models in the line of inlets are as follows:

1. EPFA 480.
2. EPFA 700.
3. EPFA 1200.

Each model Available in several variations, the differences lie in the power of the heater.

The characteristics of EPFA inlets are as follows:

Installation features

Devices of both lines are usually mounted horizontally, in the ceiling space. Installation is carried out using self-tapping screws: the housing is attached to the surface using 4 mounting brackets. Vertical installation (on the wall) is also possible, but is practically not used.

Air duct lines are laid from the installed device through which air will be removed from the room (or rooms) and supplied to it.

During installation, it is necessary to provide access to the service hatch.

Buying household appliances is half the battle. It is important to know how to perform installation correctly. If you want to save on the services of a specialist, we will tell you how to install an Electrolux dishwasher. You will learn the details of doing the work yourself, which you will not find in the instructions.

First, decide on the size of the dishwasher. If you have small family, then feel free to choose a compact option for 6-8 sets of dishes. When integrating the Electrolux PMM into a finished set, it is important to choose the right place:

1. Compact model. Fits perfectly under the sink, just needs to be installed special siphon. Proximity to communications is a big plus. The machine can also be placed on a countertop, because its dimensions are no larger than a microwave oven.
2. Built-in narrow PMM. Fits in one of the closets kitchen set. It is advisable to choose a place to the right or left of the sink. If you buy equipment and order new kitchen, then a cabinet for a dishwasher is provided in advance.
3. Freestanding model. Place it in a convenient place. You can move the cabinets apart and install equipment or put it in a free corner.

It is important to place the Electrolux brand dishwasher level. The tilt to one side should not exceed two degrees.

You can remodel the cabinet in the suite yourself. To do this, remove the door from its hinges, remove all shelves and the back panel. Or make holes for hoses in the side wall.

How to avoid losing your warranty

Please read the instructions carefully before installing the machine yourself. Each manufacturer indicates acceptable standards when connecting equipment. Most dishwashers are not allowed to be connected to hot water. This leads to damage to hoses and filters.

If the PMM breaks down due to connection to a hot water supply, then you can’t count on warranty repairs.

Another dangerous point is the connection to the electrical network. It is prohibited to connect powerful equipment to regular old outlets without a voltage stabilizer, or to connect it to the same outlet as an electric stove.

Wiring

If your network is not prepared, call a specialist; you should not deal with electricity yourself. What work is ahead:

1. Wall chipping. A puncher prepares a groove into which a three-core copper wire is laid.
2. Installation of a European socket. Since the PMM cord is quite short, it is recommended to place the socket at a level of 45 cm from the floor. It must be moisture resistant and grounded.
3. Connecting a 16A power breaker. It ensures stable operation of the equipment.

Connecting and placing the dishwasher

Before starting work, prepare the components:

• Siphon with two or three drainage outlets. Additional fittings are useful for connecting other devices. If not needed, one fitting can be closed with a plug.
• Tee made of brass, bronze or metal-plastic. ¾ inch thread. If the tee does not have a shut-off valve, then purchase one separately.
• Filter. Installed to purify water from impurities.
• Hoses required length, if the standard ones are not enough.
• Fumku. High-quality fum tape waterproofs connections.

Tools you need are an adjustable wrench, pliers, and a screwdriver.

Act in correct sequence. First you need to connect the drain, then the water supply and power supply. Judge for yourself what is more convenient for you: connect all the outputs at once and install the dishwasher in the cabinet, or place it in place and then start connecting.

Working with drain

Attach the drain hose to the outlet of the siphon. It should bend at the top so that waste water does not enter the PMM bunker. The bottom bend (which comes from the machine) should be short and deep.

Water connection

Have you already decided which water supply to connect to? About connecting to hot water read our article. First of all, close shut-off valve. Remove from water supply outlet kitchen faucet and old insulation. Install the brass tee. Connect a mixer, a coarse filter, and a dishwasher hose to the outputs (you can use a connecting tube - a hose). All connections are carefully insulated with fum-leta (wrap at least 10 times along the thread).

Additionally, install a ball valve if it is not on the tee.

All that remains is to plug the plug into the socket. Now you can do a test run and check dishwasher in action. Open stopcock and make a test run of the PMM without dishes. Make sure there are no leaks anywhere.

It is not difficult to connect the Electrolux dishwasher with your own hands. The main thing is to act consistently and follow the instructions. A video on the topic will help you:

The Swedish manufacturer Electrolux (Electrolux) produces not only household and climate control equipment, but also ventilation equipment. Air handling units are in particular demand today. These are compact, extremely easy-to-use devices that are highly economical and reliable.

Inflow exhaust unit Electrolux. Types and characteristics

The Yanvent online store offers to buy Electrolux ventilation devices in fully equipped at prices from the manufacturer.

Electrolux epvs perform the following functions:

• Heat recovery with efficiency up to 90%
• Create a comfortable microclimate
• Protects against dust, particles, smoke and odors
• They work quietly, absorbing noise from the street
• Minimum energy consumption

The catalog includes a series of ventilation units with recovery and electric heater, which are designed for air flow from 200 to 2000 m3/hour

Electrolux Epvs 200 is a modern recuperative device designed for ventilation of rooms up to 80 m2.

Epvs 350 is a supply and exhaust unit with heat recovery function. The air is heated without significant costs electricity.

Epvs 650 - best option to create an efficient and economical supply and exhaust system. To increase productivity, the equipment can be supplemented with an auxiliary heater.

Calculation of heater power

Device model Heater power, kW

• Epvs 200 - 1.8
• Epvs 350 - 2.4
• Epvs 450 - 5.0
• Epvs 650 - 6.0
• Epvs 1100 - 9.0
• Epvs 1300 - 12.0

Unlike the Electrolux epvs 650 model, the epvs 1100 installation has increased power. Through the use of a heat exchanger membrane type part of the heat from the removed air, together with moisture, is transferred through the surface of the recuperator to the supply cold air. At the same time, the efficiency of the installation is up to 90%.

Features and advantages of PES installations

In the production of PPV installations Star EPVS 200, a series of innovative technologies were introduced:

1) All structural elements The systems are compactly housed in a galvanized steel housing, thereby minimizing vibration of moving elements and reducing noise levels.

2) The units use an innovative hexagonal-shaped heat exchanger, which has a heat exchange surface that is 30% larger than that of standard ventilation devices. This made it possible to achieve efficiency of up to 90% without installing additional heaters.

3) Built-in thermal contacts provide motor protection that automatically restarts when temperatures exceed 125 degrees.

4) The system is equipped with electronic anti-icing protection during the cold season.

5) The integrated automation system makes operating the devices simple and convenient. All necessary parameters can be set using the remote control with LCD display.

High-quality and reliable Electrolux installations will be a useful acquisition and will delight efficient work and crystal clean air for many years.

The Electrolux STAR EPVS supply and exhaust unit is designed to supply fresh air to the room, purify the supplied air, and remove exhaust air. All STAR EPVS air handling units are equipped with a membrane-type plate heat exchanger. The plate recuperator allows you to significantly reduce energy costs for heating and humidifying the supply air. This happens as follows: fresh air, passing through the recuperator, increases (or decreases) its temperature, exchanging heat and moisture with the exhaust air. Fresh and removed exhaust air do not have direct contact and do not mix, thereby the incoming air remains uncontaminated. A special membrane of the recuperator allows only water molecules to pass through from the exhaust air, leaving behind all contaminants. This type of installation is ideal for creating an apartment ventilation system or country house.

Heater power is designed for maximum expenses air. If the flow rate is less than the maximum, then the heater power is determined as follows:

N = -0.33 × (T+15) × L,

Where N – heater power, kW

T – calculated minimum air temperature for a given region, °C

L – air flow, m3/h

Electric heater connected to the appropriate terminals via a magnetic starter (contactor). The installation controller sends a signal to turn on the heater at an outside air temperature of -10°C. Before the specified temperature is reached, supply air heated by a recuperator. Electrolux STAR EPVS air handling units use a plate heat exchanger, the efficiency of which is from 85% (STAR ​​EPVS 200) to 90% (in all other sizes).
You can calculate what air temperature will be after the recuperator using the formula:

t=(t 1 -t 2 )*k+t 2

Where:
t - temperature after the recuperator,
t 1 - indoor temperature,
t 2 - supply air temperature to the recuperator ( outside temperature air),
k is the efficiency of the recuperator.

For example, in a ventilated room, the air temperature is 20°C, the street air temperature is -5°C, the air ventilation system is built on an Electrolux STAR EPVS-350 supply and exhaust unit, the efficiency of the recuperator is 90% (max).
That. According to the formula, the air temperature after the recuperator will be equal to:

T=(20-(-5))*0.9+(-5)=17.5°C

This calculation is approximate, because the actual temperature will depend on many parameters and will be lower than the calculated one.

Air handling units Electrolux STAR EPVS can be operated without a heater, but only up to an outside temperature of -15 °C. When the supply air temperature is below -15 °C, the air handling unit will go into emergency mode and stop operation for 15 minutes. If after the specified time the air temperature does not increase, the installation will remain in emergency mode.

One of the most important parameters of this series of air handling units with heat recovery is its high energy efficiency due to the transfer of thermal energy from the removed warm air to the supply cold air.

The efficiency of modern membrane recuperators used in these installations reaches 70%.

The use of Electrolux EPVS-1100 air handling units with heat recovery is especially relevant for our climate, when winter period The year lasts 7-8 months a year.

According to the experience of our research and calculations, the payback for air handling units with recovery occurs on average in 1.5-2 years of operation. Compared to equipment that heats supply air with electricity.

High recovery efficiency is achieved through modern technology using a membrane-type heat exchanger-recuperator with the ability to transfer part of the heat with moisture through the surface of the recuperator.

However, recovery alone is not enough for full heating, so it is necessary to install an auxiliary heater, although its power is already significantly less than what would be needed to heat the same volume of air without using recovery.

Control

Control of this equipment model is absolutely simple. Enabling/disabling and adjusting the necessary parameters is carried out using the control panel:

Advantages and disadvantages of this model of air handling unit

Recommendations for selecting an air handling unit:

It should be noted that this method selection is very indicative and suitable for designing complex ventilation systems.

Aerodynamic characteristics of the installationElectroluxEPVS-1100

If it is necessary to use a longer network of air ducts and there will be high losses, the manufacturer recommends using special booster fans:
