Detailed description of the invention
Technical scheme of the present invention is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
A kind of air conditioning control method, when air-conditioning is in heating condition, extracts at least part of liquid refrigerants in the refrigerant loop after condenser and makes this part liquid refrigerants not participate in working cycles.By emulating in a large number and testing discovery, heat Energy Efficiency Standard in order to what reach setting, the cooling medium charging amount of described heating condition is less than the cooling medium charging amount of cooling condition.Therefore, make this part liquid refrigerants not participate in working cycles by the Extraction parts liquid refrigerants when heating state, that effectively can improve air-conditioning heat efficiency, thus improve the annual seasonal energy efficiency of air-conditioning.
Concrete, can by the efficiency of testing inspection air-conditioning, thus the setting refrigeration refrigerant volume P2 of the setting determining when heating situation in refrigerant loop when heating refrigerant volume P1 and refrigeration situation, when drawing heating condition further, the at least part of liquid refrigerants in the refrigerant loop after condenser need be extracted and make this part liquid refrigerants not participate in working cycles, and when drawing heating condition further, the refrigerant △ P=1 ± 30% × P2-P1 that need propose from refrigerant loop.To realize air-conditioning respectively in the optimum cooling medium charging amount of cooling condition and heating condition, effectively promote the efficiency of air-conditioning system device.
Additionally provide a kind of air-conditioning system device, in order to perform described air conditioning control method, it comprises outdoor heat exchanger 101, throttling arrangement 106 and four-way change-over valve 102, indoor heat exchanger 104 and compressor 103, also comprise refrigerant device for storing liquid, described refrigerant device for storing liquid is for extracting at least part of liquid refrigerants in the refrigerant loop after condenser.
Described refrigerant device for storing liquid is arranged on indoor heat exchanger 104 and heats between outlet when flowing to and throttling arrangement.Volume=1 ± 30% × refrigeration refrigerant volume the P2-of described refrigerant device for storing liquid heats refrigerant volume P1, and the volume of described refrigerant device for storing liquid is got little, then have reduction effect to the effect of efficiency; Get greatly, then complete machine cost can have been caused to increase and be subject to the restriction of outer cage body dimensional space; Further, the volume=setting refrigeration refrigerant volume P2-setting of described refrigerant device for storing liquid heats refrigerant volume P1.
Concrete, described refrigerant device for storing liquid is refrigerant fluid reservoir, and as shown in Figure 2, described refrigerant device for storing liquid is refrigerant fluid reservoir 105, and it comprises refrigerant fluid reservoir tank body 201.The existing refrigerant fluid reservoir be applied in air-conditioning, fluid reservoir is provided with import and outlet, and structure is comparatively complicated, and manufacturing cost is higher, is not easy to directly apply in air-conditioning system device of the present invention; Therefore, for simplifying liquid storage tank structure, further, described refrigerant fluid reservoir tank body 201 is only provided with a refrigerant fluid reservoir connector, described refrigerant fluid reservoir tank body 201 is vertically placed, and refrigerant fluid reservoir connector is positioned at the bottom of refrigerant liquid storage tank body 201.Described refrigerant fluid reservoir connector place is connected with the tube connector 202 be connected with refrigerant loop.
Concrete, the height of described refrigerant fluid reservoir 105 is H, and described tube connector 202 stretches into the length L≤1/3H of fluid reservoir.Set the best during setting refrigeration refrigerant volume P2-heating condition during the volume=1 ± 30% × cooling condition of described refrigerant fluid reservoir 105 and heat refrigerant volume P1.
Outdoor heat exchanger 101 in refrigerant loop connects throttling arrangement 106 and four-way change-over valve 102 respectively, and described four-way change-over valve 102 connects indoor heat exchanger 104, and described four-way change-over valve 102 is parallel with compressor 103.
During concrete enforcement, described refrigerant fluid reservoir tank body 201 is vertically placed, and refrigerant fluid reservoir connector is positioned at the bottom of refrigerant fluid reservoir tank body 201.Described refrigerant fluid reservoir connector place is connected with the tube connector 202 be connected with refrigerant loop.Described tube connector 202 is welded in refrigerant fluid reservoir connector place.
Excessively dark in order to prevent tube connector 202 from going deep into refrigerant fluid reservoir tank body 201, concave surface is formed on the weld of described tube connector 201 and the bottom of refrigerant fluid reservoir tank body 201, for preventing the refrigerant entered when being deposited in cooling condition near tube connector 201, therefore the tip edge of described tube connector 202 is not higher than the height of welding position.
When running heating condition, outdoor temperature is lower than indoor temperature, stored in the refrigerant of liquid state in described refrigerant device for storing liquid, and stored in the volume of liquid refrigerants be △ P=1 ± 30% × cooling condition time setting refrigeration refrigerant volume P2-heating condition time set the best and heat refrigerant volume P1.
As shown in Figure 1, when operation of air conditioner heating condition, if the dotted arrow indication loop direction in Fig. 1 is heating mode, outdoor temperature is lower than indoor temperature, and the heat release after indoor heat exchanger 104 of high pressure refrigerant, becomes highly pressurised liquid refrigerant.
Simultaneously when air-conditioning is installed, in order to reach indoor heat exchanger 104 after the heat exchange, liquid refrigerants in refrigerant loop can flow into compressor 103 through throttling arrangement smoothly, therefore in indoor heat exchanger 104 to compressor 103 multiloop, belong to the mode successively reduced to install, therefore when described highly pressurised liquid refrigerant flows through refrigerant device for storing liquid, because it exists enough drops, so high pressure refrigerant liquid riddles in refrigerant device for storing liquid in liquid form.
When operation of air conditioner cooling condition, if solid arrow direction in Fig. 1 is that the kind of refrigeration cycle of refrigeration mode is reverse, outdoor temperature is higher than indoor temperature, and high pressure refrigerant is heat absorption after indoor heat exchanger 104, vaporization becomes the steam of low-temp low-pressure, becomes low temperature and low pressure steam refrigerant.
When described low temperature and low pressure steam refrigerant flows through refrigerant device for storing liquid, because the relation of pressure differential, be deposited in refrigerant device for storing liquid in the form of a vapor, and because its density of refrigerant of steam state is lower, the difference △ P accounting for the best condensation groundwater increment of the situation of heating and refrigeration situation is less, when not affecting hot cold operating mode, the refrigeration efficiency of refrigerant in refrigerant loop.
In sum, based on the difference of indoor/outdoor temperature-difference under heating condition and cooling condition, by the indoor heat exchanger outlet heating the flow direction in system, a refrigerant fluid reservoir is set, thus refrigerant unnecessary under system heating condition is stored in refrigerant fluid reservoir, to make under heating condition cooling medium charging amount in heat exchanger reach best, and then increase the heat exchanger heat exchange efficiency of heating condition, reduce system high pressure, reduce compressor 103 power, final lifting air-conditioning system device efficiency.
Below know-why of the present invention is described in conjunction with specific embodiments.These describe just in order to explain principle of the present invention, and can not be interpreted as limiting the scope of the invention by any way.Based on explanation herein, those skilled in the art does not need to pay performing creative labour can associate other detailed description of the invention of the present invention, and these modes all will fall within protection scope of the present invention.
