Air-valve 4 enters after interior wind pushing cavity 14 is directly sent to interior again, and now air is not passed through heat regenerator 2 and is sent into indoor sky
Gas is full return air.
When return air air-valve 4, air intake by-passing valve 3 and air draft by-passing valve 5 are opened, the return air sent from interior is divided into two
Part, a part of return air is after return air air-valve 4, with the fresh air through air intake by-passing valve 3 and the entrance of air intake opening 163 in interior wind pushing cavity
Mixing is sent into indoor in 14；Another part return air discharges outdoor through air draft by-passing valve 5 and air draft opening 164.Now air does not flow
Through heat regenerator 2 and indoor air is sent into as fresh air mixing, and regulation air intake by-passing valve 3 can adjust fresh-air volume, adjust air draft
By-passing valve 5 can adjust the air quantity of air draft, have adjusted the return air air quantity mixed with fresh air accordingly.
When air intake by-passing valve 3, air draft by-passing valve 5 and return air air-valve 4 are turned off, outdoor fresh air and indoor return air cross-current
Cross heat regenerator 2 and complete heat exchange, fresh air feeding is indoor, return air discharge is outdoor, and this Airflow is through heat regenerator 2 and is sent into room
Interior air is all-fresh air.
When return air air-valve 4 open and resistance be present, close air intake by-passing valve 3 and air draft by-passing valve 5 when, adjust return air air-valve
4 aperture, when making the resistance of return air air-valve 4 and the roughly the same resistance of heat regenerator 2, an indoor return air part and outdoor fresh air are intersected
It is outdoor to flow through discharge after heat regenerator 2 completes heat exchange, another part return air and feeding after the fresh air mixing after heat exchange are indoor.Now
Air flows through heat regenerator 2 and is sent into indoor air and mixed for fresh air, and the aperture of regulation return air air-valve 4 can adjust feeding
Indoor fresh air and return air ratio, the fresh air and return air mixed proportion by heat regenerator 2 are also have adjusted indirectly, improve recuperation of heat
The organic efficiency of device.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
All any modification, equivalent and improvement made within refreshing and principle etc., should be included in the scope of the protection.
