Air climatic systems - the usual part of the engineering filling of many private houses of the United States and Canada - begin to gradually introduce into life of Russians. Overcomes of this equipment will help us to deal with one particular example.
Air climatic systems appeared as a result of the development of air heating technology. It suggests that all air, filling the room, passes several times a hour through the air heater. Thanks to this in the winter rooms, the desired temperature is supported. The idea was born to use circulating air masses to deliver not only heat to the room, but when it is necessary, moisture, moisture, oxygen and simply remove contaminants. To implement it, they invented the air heating system with additional modules: blocks for cooling, moisturizing, cleaning air and organizing the supply and exhaust ventilation. A results of the air heating system turned into an air climate system, which ensures the comfort of the microclimate in housing throughout the year.
Individual approach
One of the similar systems is installed in a two-storey frame-panel country house with an area of 208m2, built in 2004. In Sergiev Posad, not far from Trinity-Sergiye Lavra. It provides users of temperature and humidity specified by users, individual for each of the three cottage zones: the first floor, the second floor, the winter garden. The system modes are configured in accordance with the habits and the schedule of the household day. For example, in the winter it automatically reduces the temperature at night, when the hosts are sleeping, and in the afternoon, if the house is empty, and a few hours before their return or early in the morning, it starts to work so that at the right time the cottage's microclimate has become most comfortable at the right time. In the summer, the system during the daytime (in the absence of people) is less intensively cools the rooms, and in the evenings quickly brings the temperature to the norm. The temperature and relative air temperature and relative humidity are mainly maintained.

The unit includes an air processing unit located in the boiler room and regulating "Conditions" of the air driven through it, which is closed from the rooms over the network of discharge, and returns over the supply air ducts. Fresh air house supplies mechanical ventilation based on energy-saving supply-exhaust installation. Only small vents, as well as wall-mounted programmable control panels are visible on the floor and walls of the building on the floor and walls.
The air climate system owners of the house chose after the equipment features in detail. Even a typical project of the house was selected taking into account the characteristics of the installation of this system (the presence of free space in the undergrounds for laying air ducts, highly efficient thermal insulation of the enclosing structures of IT.P.). The crucial role played the ability of the air climate system automatically, virtually no host intervention, all year round controls the parameters of the air: temperature, humidity, air purity, that is, solve the problem of climation, without applying several independent systems - boilers, air conditioners, humidifiers and air cleaners. Interested in the prospect of refusal from bulky heating devices, they probably could not organically fit into the interiors of the country house with its low windows. In addition, the solution was influenced by the low inertia of the equipment (the system can change the temperature in the room 10-15 ° C for only 30-40 minutes), high efficiency and efficiency.
The system project was ordered immediately in several organizations that were offered to perform it on the basis of gas air heaters of American firms Nordyne, Tempstar, Goodman, Lennox. The project of the company "STTC Service" was most fully the requirements of the House owner - she was entrusted to her implementation. All work was finished after 2 months after the first appeal of the owner of the housing.
Modular principle
To cool the cottage rooms during the summer period in the air tract behind the air heater (in the course of air traffic), the evaporative block of the channel split-system Lennox is built-in. It is connected to the outer compressor-capacitor block, located outside the building, in the courtyard, in the door to the outer compressor condenser unit. It is characteristic that the split system can not only cool, but also work in air drain mode, removing excessive moisture from the house.
However, in the arid summer, as well as the whole winter, the air in the rooms often needs not in drainage, but in moisture. To increase its relative humidity, the air preparation unit equipped the GENERAL FILTS (USA) surface humidification module. It is mounted at the entrance to the air heater and consists of a cassette (the so-called irrigated nozzle) with a hygroscopic material on which the filtered water from the water pipeline is supplied through the water distributor. The material of the nozzle absorbs moisture, and when passing through it, the air is moistened.
Purification of air from particles up to 0.01 microns is carried out by the electrostatic filter of Five Seasons (Canada). It is built into the air tract in front of the air heater, and through it the entire amount of the filling air cottage passes. Thanks to him, the content of dust, the dispute of microorganisms and plants, pollens, bacteria, pollution, tobacco smoke in the air of the premises are insignificant. The only task of the hostess is not to forget at least once every 6 months to wash the electrostatic filter chamber.
The supply and exhaust air ducts are assembled from rectangular and round-section pipes and shaped elements made of galvanized steel. They are manufactured in accordance with the requirements of Air Conditioning Contractors of America (ACCA) in Russia, on the production base of StTS Service. From the boiler pipe goes to rooms - overlaps, technical underground and for falseland. The vests of air ducts feeding the prepared air into the premises are set by diffusers (squabbles, or they are called installers, "shoes"), which reduce the speed of the air flow (approximately 1-1.5 m / s). They were located under the windows and in the outer walls, flush with the first floor, and covered with switching lattices with rotary slats. The rest of the latter can be changed the direction of air supply. The exhaust air fence comes from the lower area of the premises. The outputs of the return air ducts on the rashlock and on the floor are decorated with air-actuated lattices, organically fit into the design of the room.
Individual automatic control and temperature control in each of the cottage zones are carried out by means of an intelligent zone control system. Signals from thermostats that are in the house, and other sensors come to its "brain" - a microprocessor control unit that doses the volume of the prepared air supplied to the zone. The last operation is implemented as follows: the electric valves overlap the flowing section of the air ducts that feed the treated stream, as the temperature specified temperatures are shown.
