The working principle of net for air-source heat pump units 600 is easily described below with reference to above structure description.
Before operation or in operational process, the control system of net for air-source heat pump units exists net for air-source heat pump units according to setting
Heat preserving sound deadening room 100 indoor temperature sensor indoor temperature value detected controls 300 (specially companion of the first preheating mechanism
The torrid zone 320), the operating status of the second preheating mechanism 500 (referring specifically to valve), meanwhile, also according to the sensor institute being located outside
The outdoor temp angle value of detection adjusts the tilt angles of multiple window leaves 220 of louver body 200.In present embodiment, air
Source heat pump unit is mounted in outdoor temperature extremely cold environment below lower than -25 °, therefore the window leaf 220 of louver body 200 is preferred
It is set as tilting down 45 °, the first preheating mechanism 300 and the second preheating mechanism 500 are in operating status.
Outdoor air enters in heat preserving sound deadening room 100 via louver body 200, is then flowing through the first preheating mechanism
By 320 heat temperature raising of heating tape thereon when 300；Air after flowing through the first preheating mechanism 300 is flow at wind deflector 400, greatly
Partial air will receive the blocking of wind deflector 400 and turn back, and continue via the surrounding of wind deflector 400 towards air source heat pump machine
The air inlet flowing of group 600, only fraction air can continue via the through-hole 410 on wind deflector 400 towards air-source
The air inlet of heat pump unit 600 flows；Air after flowing through wind deflector 400 continues to run to the second preheating mechanism 500, via
The heat exchanger 510 of second preheating mechanism 500 heats the air in the air and heat preserving sound deadening room 100 that flow through it；It flows through
Air after second preheating mechanism 500 enters net for air-source heat pump units 600 via the air inlet 113 of net for air-source heat pump units 600
It is interior and with the evaporator of net for air-source heat pump units 600 610 carry out heat exchange, occur heat exchange after air become Cryogenic air,
The Cryogenic air drains into the outside in heat preserving sound deadening room 100 via the air draft air hose 610 of net for air-source heat pump units 600.
It is mainly had the following beneficial effects: using the installation system of net for air-source heat pump units of the present invention
The first, by the way that the adjustable louver body of vane angle is arranged at the air inlet 113 in heat preserving sound deadening room 100
200, its inflow direction can be carried out respectively and be changed to the air flowed into heat preserving sound deadening room 100, can avoid under extremely cold environment
Air flows into outdoor air more uniformly in heat preserving sound deadening room 100 from frontal impact net for air-source heat pump units, can also reduce room
Outer air generated noise when entering in heat preserving sound deadening room 100；
The second, outdoor air can successively flow through the first preheating mechanism 300 and the second preheating after entering in heat preserving sound deadening room 100
Mechanism 500 can heat the air in heat preserving sound deadening room 100 via the two preheating mechanisms, make heat preserving sound deadening room 100
The interior pre- air themperature into net for air-source heat pump units 600 is improved compared to the temperature of outdoor air, is conducive to improve air
The Energy Efficiency Ratio of source heat pump unit, meanwhile, 600 frosting of net for air-source heat pump units is also avoided, 95% or more defrosting is reduced；
Third, due to being provided with wind deflector 400, Ke Yizeng between the first preheating mechanism 300 and the second preheating mechanism 500
Add the tortuosity in air circulation path, and then improve the two preheating mechanisms to the heating effect of air, makes to enter air-source heat
Air themperature in pump assembly 600 significantly improves, and then is conducive to improve the Energy Efficiency Ratio of net for air-source heat pump units, fully ensure that-
25 DEG C of air source heat pumps, can also operate normally under -38 DEG C of environment temperatures；
4th, the drop of setting opposite with the air outlet of air draft air hose 610 is set by the top in heat preserving sound deadening room 100
The mechanism that makes an uproar 800, the air that the exhaust outlet by air draft air hose 610 can be discharged effectively are intercepted, and then guarantee noise reduction effect
Fruit.
5th, louver body 200, the first preheating mechanism 300, the second preheating mechanism 500 control module and air
The control system signal of source heat pump unit 600 connects, can (outdoor temperature, outdoor wind-force, room temperature as the case may be
Deng) come control they operating status realize intelligent control, ease of use can be improved, while air source heat pump also can be improved
