The embodiment of the present invention is described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning to end
Same or similar label indicates same or similar element or element with the same or similar functions.Below with reference to attached
The embodiment of figure description is exemplary, it is intended to is used to explain the present invention, and is not considered as limiting the invention.
A kind of air-conditioner control system and method for it is proposed of the embodiment of the present invention described with reference to the accompanying drawings.
As shown in Fig. 1 to 2, the embodiment that technical solution provides according to the present invention, air-conditioner control system provided by the invention,
Including evaporator 2, compressor 1, temperature collecting module 5 and control module 6.
Wherein further include expansion valve 3 and condenser 4, the workflow of air-conditioning is as follows:
The refrigerant compression of cryogenic gaseous is the gaseous state of high temperature and pressure by compressor 1, is then delivered to condenser 4, is dissipated in condenser 4
Become room temperature liquid after heat, the refrigerant of room temperature liquid through capillary enters evaporator after coming out from condenser 4, due to capillary
Narrow space, refrigerant enter 2 space of evaporator and become larger suddenly, and pressure die-offs, and the refrigerant of liquid, which absorbs heat, to be vaporized, from evaporator
Become cryogenic gaseous after the 2 a large amount of heats of absorption, the refrigerant of cryogenic gaseous, which enters compressor 1, to be continued to compress, to complete to follow
Ring.
When refrigeration, the refrigerant compression of cryogenic gaseous is the gaseous state of high temperature and pressure by compressor 1, is then delivered to outdoor condensation

Income level.
In cooling mode, control module adjusts air-conditioning stopping temperature and reduces with the raising of room temperature air-conditioning, controls
Molding block adjusts Income level and increases with the raising of room temperature, to increase the operating temperature range of compressor.
It being inversely proportional specifically, air-conditioning stops temperature with room temperature, room temperature is higher, and it is lower that air-conditioning stops temperature, such as from 3 DEG C
Drop to 2 DEG C；Income level ratio directly proportional to room temperature, room temperature is higher, and air-conditioning stopping temperature is higher, such as from
4 DEG C are increased to 5 DEG C of to be that the operating temperature range of compression DEG C increases to 5 DEG C to 2 DEG C from 4 DEG C to 3, to increase compressor
The single working time, increase refrigerating capacity, to achieve the purpose that cooling faster, while also avoiding frequently opening for compressor
Stop.It is not high to the refrigeration demand of air-conditioning when room temperature is low, at this point, improving the stopping temperature of air-conditioning, for example it is raised to from 2 DEG C
3.5 DEG C, reduce the start-up temperature of air-conditioning, for example drop to 4 DEG C from 4.5 DEG C, at this time the operating temperature range of compressor from 2 DEG C to
4.5 DEG C are reduced to 3.5 DEG C to 4 DEG C, reduce the working time of compressor, reduce its refrigerating capacity, so as to avoid refrigerating capacity surplus
It needs to introduce a large amount of hot winds to be mixed, is transported to the indoor temperature fluctuation for mixing wind, shadow after leading to mixing because of hot blast temperature fluctuation
Ring body-sensing.Meanwhile also reducing energy consumption.
In a heating mode, the control module adjusts the air-conditioning and stops temperature with the liter of the room temperature air-conditioning
High and increase, the control module adjusts the Income level and reduces with the raising of the room temperature.Air-conditioning stops
Only temperature is directly proportional to room temperature, and Income level is inversely proportional with room temperature.When air-conditioning heating demand is high, increase pressure
The operating temperature range of contracting machine, such as DEG C increase to 5 DEG C to 2 DEG C from 4 DEG C to 3, so that air-conditioning is faster met heating needs.Work as sky
When modulation heat demand is lower, the temperature range of its compressor is reduced, to reduce air-conditioning heating amount, avoids the waste of energy.
Wherein, control module is additionally provided with air-conditioning limit stopping temperature and air-conditioning limit start-up temperature, and air-conditioning stops temperature
It must not stop temperature lower than the air-conditioning limit, Income level must not be higher than air-conditioning limit start-up temperature, to meet to steaming
Hair device temperature is protected, and evaporator icing or frosting are avoided.
Wherein, the control system of the present embodiment further includes cooling system of vehicle and warm-air exchanger 7.Cooling system of vehicle
It can be vehicle motor cooling system, be also possible to electric generator of vehicle cooling system, it is cooling to be also possible to vehicle traction motor
System or power battery cooling system or any combination between them.The coolant liquid of cooling system of vehicle is in warm wind
Heat exchanger internal circulation can heat fresh air, return air or mixed wind.Under refrigeration mode, when air conditioner refrigerating ability is superfluous,
When the temperature of return air or mixed wind is too low, warm-air exchanger can be flowed through and heated.It, can be to as auxiliary under heating mode
Heating system heats together with air-conditioning, can also shut down the compressor of air-conditioning, directly be carried out using the heat of cooling system of vehicle
Heating, meets heating needs.
As shown in Fig. 2, fresh air 9 and return air 10 realize sky through air blower 11 after mixing in proportion through mixed wind control valve 12
Adjust wind system circulation.Specifically, mixing distinguished and admirable through 2 surface of evaporator, flowed through at air-conditioner air outlet after becoming cold state, wherein warm
Wind heat exchanger 7 can use air of the heat convection of vehicle itself after evaporator surface freezes and be heated, and valve 8 can be with
The ratio that control passes through the wind of warm-air exchanger.When indoor refrigeration demand deficiency can in the case that compressor output is superfluous
To pass through the opening size of control valve 8, the heating to cold wind is realized, to meet indoor temperature requirements.Mixed wind is passing through steaming
Become air conditioning exhausting 13 after hair device 2 or evaporator 2, warm-air exchanger 7 and is transported to interior.
Wherein, warm-air exchanger 7 and vehicle heat source carry out heat exchange, and vehicle heat source includes engine, driving motor etc., by
It is affected in the temperature of vehicle heat source by operating condition, it is uneven so as to cause the cold air heating degree for flowing through warm-air exchanger 7, from
And lead to the temperature fluctuation of air conditioning exhausting 13.In the air-conditioner control system of the embodiment of the present invention, by adjusting evaporator protection
Temperature changes with indoor temperature change generated in case, realizes fixed displacement compressor refrigerating capacity as the demand of user is adjusted, thus
Effectively prevent the temperature of air conditioning exhausting 13 caused by needing to be heated by warm-air exchanger 5 in refrigeration demand deficiency
It fluctuates excessive, influences user experience.
Wherein, the mode that control module 6 can be adjusted according to artificial setting or intelligently adjusts outdoor fresh air 9 and air-conditioning returns
The mixed proportion of wind 10, to meet the indoor needs to air themperature or ventilation.
Wherein, the air-conditioner control system of the embodiment of the present invention, compressor 1 used can be fixed displacement compressor.Fixed row
The raising proportional with the raising of the revolving speed of engine or the revolving speed of motor of the capacity of capacity compressor.The present invention is implemented
The air-conditioner control system of example achievees the purpose that adjust air conditioner refrigerating or heats power by adjusting evaporator protection temperature.Together
When, it can effectively slow down the stop frequency of compressor.
