Control method and a kind of air-conditioner with refrigerant heating function of a kind of air-conditioner with refrigerant heating function proposing according to the embodiment of the present invention are described with reference to the accompanying drawings.
Fig. 1 is the structure flow chart of the air-conditioner with refrigerant heating function of one embodiment of the invention proposition.As shown in Figure 1, this air device comprises compressor 1, cross valve 2, outdoor heat exchanger 3, refrigerant heater 4, throttling arrangement 5 and indoor heat exchanger 6.Wherein, refrigerant heater 4 is connected in series between indoor heat exchanger 6 and outdoor heat exchanger 3, particularly, is connected in series between throttling arrangement 5 and outdoor heat exchanger 3.
In the time that startup air-conditioner heats, the flow direction of refrigerant in air-conditioner is such: compressor 1 → cross valve 2 → indoor heat exchanger 6 → throttling arrangement 5 → refrigerant heater 4 → outdoor heat exchanger 3 → compressor 1.Wherein, in indoor heat exchanger 6, the external heat release of refrigerant, namely gives room heat supply.
In one embodiment of the invention, as shown in Figure 2, this air-conditioner also comprises controller 7 and temperature inductor 8.Wherein, temperature inductor 8 is arranged on outdoor heat exchanger 3, for the evaporating temperature of sensing chamber's external heat exchanger 3 after heating at startup air-conditioner.Controller 7 is connected with temperature inductor 8, controller 7 is for starting air-conditioner and judging after heating the evaporating temperature of the outdoor heat exchanger 3 that temperature inductor 8 detects, and in the time that being less than or equal to the first preset temperature t1, opens the evaporating temperature T3 of outdoor heat exchanger 3 refrigerant heater 4 so that refrigerant is heated, and in the time that being more than or equal to the second preset temperature t2, the evaporating temperature T3 of outdoor heat exchanger 3 closes refrigerant heater 4, wherein, the second preset temperature t2 is greater than the first preset temperature t1.Preferably, in a concrete example of the present invention, the first preset temperature can be-10 to 1 DEG C, and the second preset temperature can be 1 to 5 DEG C.
In an embodiment of the present invention, temperature inductor 6 detects the evaporating temperature of outdoor heat exchanger 3 after arriving the first Preset Time m1 in the air conditioner heat-production time.Wherein, preferably, the first Preset Time can be 3 to 20 minutes.
In one embodiment of the invention, compressor 1 is frequency-changeable compressor.Wherein, in the time that startup air-conditioner heats, compressor 1 moves with first frequency h1, and is opening refrigerant heater 4 rear compressors 1 with second frequency h2 operation, and wherein, second frequency h2 is less than first frequency h1.Particularly, first frequency can be 50Hz to 150Hz, and second frequency can be 4Hz to 50Hz.

S505, opens refrigerant heater, and refrigerant heater is opened heating power, and the evolution of heat and refrigerant carry out heat exchange, improves evaporator refrigerant temperature and pressure so that frost layer above outdoor heat exchanger is melted.
S506, compressor moves with second frequency h2.That is to say, the running frequency of compressor is reduced to h2 operation by h1, and to avoid evaporating temperature too high, compressor horsepower is excessive to break down.Wherein, second frequency h2 is less than first frequency h1.In an example of the present invention, second frequency h2 can be 4Hz to 50Hz.
S507, judges whether the evaporating temperature T3 of outdoor heat exchanger is more than or equal to the second preset temperature t2, and judges whether that the continuous retention time reaches for example m2 minute of the second Preset Time.If T3 is more than or equal to t2, and accumulated running time exceed m2 minute, carry out next step.If not, return to step S507, proceed judgement.Wherein, the second Preset Time m2 can be 0.5 to 10 minute.
Or S508, judges whether compressor is greater than m3 minute with the time of second frequency h2 accumulative total operation, and wherein, m3 is greater than m2, can be 12-18 minute.If so, perform step S509; If not, return to step S507.
That is to say, two conditions are respectively: T3 is more than or equal to t2, and accumulated running time exceedes m2 minute; Compressor is greater than m3 minute with the time of second frequency h2 accumulative total operation.If can not meet one of them in above two conditions, stay at step S507, and the cumulative time.
S509, closes refrigerant heater, finishes defrost process.
