Abstract

FIELD: heating.

SUBSTANCE: economiser of window unit includes heat insulating housing in which there is heat exchanger with cold and warm developed sides respectively. End parts of heat exchanger are connected to holes of insertion tubes with removable controlled valve. Insertion tubes have air inlet and outlet connection pipes during ventilation of rooms. In removable controlled valves there are filtering soundproof inserts respectively. Removable controlled valves can be equipped with fans for forced ventilation.

EFFECT: design allows saving the heat during ventilation of rooms during winter period.

Description

The invention relates to the construction, namely, ventilation structures of the premises.

A device for ventilation of the premises is known, containing two air spaces, three wings, while the air space facing the room is filled with porous breathable material that acts as an air-air heat exchanger.

RU 2327933 IPC F24F 7/00 2008

The disadvantages of the known device for ventilation are low operational properties.

The task to which the proposed solution is directed is to increase operational properties.

The technical result is achieved by the fact that the economizer of the window unit, containing two air layers, flaps, a heat exchanger, while two layers are made in the form of a heat exchanger with warm and cold sides, located in a heat-insulating casing, mounted on the window block, the lower side of the heat exchanger is connected to the “openings insertion tubes in the window unit having removable nozzles for air inlet and outlet. In the insertion tubes there are removable adjustable valves, in the removable adjustable valves there are filtering and soundproofing inserts, as well as blocks for fans, each developed side of the heat exchanger is made in the form of heat-conducting plates or heat pipes.

The drawing shows the economizer of the window block:

The economizer of the window unit contains a heat-insulating housing 1, in which there is a heat exchanger 2 with cold and warm developed sides 3 and 4, respectively. The end parts 5 and 6 of the heat exchanger 2 are connected to the openings 7 and 8 of the insertion tubes 9 and 10 with removable adjustable valves 11 and 12. The insertion tubes 9 and 10 have nozzles 13, 14, 15, 16 for air inlet and outlet during the ventilation of the rooms. In removable adjustable valves 11 and 12 there are filtering, soundproofing inserts 17, 18 and 19, 20, respectively. Removable adjustable valves 11 and 12 can be equipped with fans for forced ventilation (not shown).

The operating principle of the economizer of the window unit is as follows.

In winter, the nozzles 13 and 14 are open. The warm air of the room enters the upper part of the nozzle 13, passes through the adjustable valve 11, rises up along the warm developed side 4, then through the adjustable valve 12 goes out through the upper part of the pipe 14.

At the same time, cold air from the street enters the lower part of the nozzle 14, passes through the soundproofing and filtering inserts 17 and 18, the adjustable valve 12, goes down along the developed cold side 3 of the heat exchanger 2, is heated by the heat of the rising air flow from the premises through another developed warm side 4 of the heat exchanger 2 and through the adjustable valve 11 and the lower part of the pipe 13 enters the room.

With a relatively small resistance to air flow in the soundproofing and filtering inserts 17 and 18, ventilation is ensured by natural convection of the air even at a temperature difference of t = 2-3 ° C. Thus, during ventilation, air heat is recovered from the premises. In the summer, using the adjustable valves 11 and 12, the nozzles 15 and 16 are opened. The nozzles 13 and 14 are closed.

The cooler air from the room through the lower part of the pipe 15 and the adjustable valve 12 enters the heat exchanger 2 and moves down the developed side 3 of the heat exchanger 2, then through the adjustable valve 11 and the lower part of the pipe 16 is thrown out. At the same time, warm air from the street through the upper part of the pipe 16, the adjustable valve 11 enters the heat exchanger 2 and rises up the developed side 4 of the heat exchanger 2, while its temperature will decrease due to heat exchange with cooler air from the premises. From the heat exchanger 2, the air stream enters the adjustable valve 12 and through the upper part of the pipe 15 enters the room. During normal ventilation in hot weather, warm air from the street enters the room, in this case it is cooled to a certain extent through the heat exchanger 2 from the air from the premises. And in winter, frosty air from the street is heated by the heat of the exhaust air from the room.

The economizer can be equipped with fan inserts. The economizer design for window units will save up to 30% of heat when ventilating the premises during the cold season and can be mounted on window units of any designs.
