Description
Technical field
The present invention relates to a kind of air-conditioner defrosting method, relate in particular to a kind of control method of heat pump air conditioner defrosting.
Background technology
Air-conditioning system is when heating operation, outdoor heat exchanger absorbs heat from outdoor environment as evaporimeter, its evaporating temperature is lower than outdoor environment temperature, when evaporating temperature is during lower than the freezing point of outdoor environment, airborne steam can condense and frosting at heat exchanger surface, heat exchanger frosting meeting increases the resistance of air stream when heat exchanger, reduce air mass flow, heat exchanger frosting has also increased heat exchange thermal resistance, this two aspect all reduces the caloric receptivity of outdoor heat exchange, heating effect variation, therefore air-conditioning system is when doing heating operation, if outdoor heat exchanger frosting, frost should be melted.
Air-conditioning system defrosting generally can transfer air-conditioning to refrigeration mode and close indoor set blower fan and defrost, and in defrosting, air-conditioner can not provide heat to room, and needs consumed power.Have, air-conditioner defrosting is too frequent, need to consume too much electric energy for Defrost operation again, also can cause heating intermittently, and room temperature fluctuation, and do not defrost for a long time, outdoor heat exchanger heat transfer effect is poor, can cause again heating effect poor.

As preferably, described defrosting mode is: the compressor of air-conditioning system and inside and outside blower fan are out of service, and by cross valve power-off, the compressor that reruns carries out Defrost operation.
As preferably, when outer disk temperature reaches 12 ℃, air-conditioning system judges that defrosting eliminates, and compressor is out of service, and air-conditioning system transfers normal heating operation to.
The beneficial effect that the present invention brings is, the present invention can accomplish in the situation of easy frosting that the heating operation time is short, is not easy in the situation of frosting the heating operation time long, and system is rationally defrosted, and improved the heating effect of air-conditioner.
Accompanying drawing explanation
Accompanying drawing 1 is a kind of control flow schematic diagram of the present invention.
The specific embodiment
Below by embodiment, and by reference to the accompanying drawings, technical scheme of the present invention is described in further detail.
Embodiment: the control method of a kind of heat pump air conditioner defrosting of the present embodiment as shown in Figure 1, in heating operation, is first set compressor continuous operating time T
n, as compressor continuous operating time T
nwhile reaching setting value, air-conditioning system enters defrosting mode by heating operation, and records defrosting time t, the compressor continuous operating time T in next cycle
n+1according to the defrosting time t in last cycle, determine, thereby determine the heating operation time.
Wherein, defrosting time t is that while entering defrosting, compressor is opened into the time that defrosting finishes.
Defrosting mode is: the compressor of air-conditioning system and inside and outside blower fan are out of service, and by cross valve power-off, the compressor that reruns carries out Defrost operation.
Compressor continuous operating time T
nalso comprise compressor continuous operating time T when air-conditioning enters defrosting first
1, when air-conditioning system enters heating operation, air-conditioning system is by sensing chamber's external environment temperature T
rdetermine compressor continuous operating time T when air-conditioning enters defrosting first
1.
Concrete control step is as follows:
Step S1: during heating operation, detect sensing chamber's external environment temperature T
rand judge that air-conditioning enters compressor continuous operating time T while defrosting first
1.
Work as T
rin the time of>=8 ℃, compressor continuous operating time T when air-conditioning enters defrosting first
1for 60min;
As 0 ℃ of < T
rduring 8 ℃ of <, compressor continuous operating time T when air-conditioning enters defrosting first
1for 80min;
Work as T
rin the time of≤0 ℃, compressor continuous operating time T when air-conditioning enters defrosting first
1for 80min.
Step S2: compressor continuous operating time T
1.
Step S3: compressor continuous operating time T when air-conditioning enters defrosting first
1while reaching setting value, air-conditioning system starts defrosting mode and defrosts, when prison detects outer disk temperature and reaches 12 ℃, after thinking that outdoor heat exchanger frost has eliminated, compressor is out of service, air-conditioning system transfers normal heating operation to, record defrosting time t now, and now period 1 defrosting finishes.
Step S4: the compressor continuous operating time of setting next cycle according to the defrosting time t in last cycle.
When t > 6min, the compressor continuous operating time T in next cycle
n+1on the basis of defrosting time t described in the last cycle, increase 10min;
When t≤6min, the compressor continuous operating time T in next cycle
n+1on the basis of defrosting time t described in the last cycle, reduce 10min.
Again enter step S2: compressor continuous operating time T
2.
Compressor continuous operating time T when second round
2reach while setting value, namely T
2=T
1+ 10min or T
2=T
1during-10min, according to step S3 operation, air-conditioning system starts defrosting mode and defrosts, when prison detects outer disk temperature and reaches 12 ℃, after thinking that outdoor heat exchanger frost has eliminated, compressor is out of service, air-conditioning system transfers normal heating operation to, record defrosting time t now.
Now again enter step S4, according to the defrosting time t recording second round, set the compressor continuous operating time T of period 3
3, so circulate, reach the object of reasonable defrosting.
When air-conditioning system translative mode or after shutting down, then while entering heating operation, compressor continuous operating time T when redefining air-conditioning and entering first defrosting
1.This air-conditioning system translative mode does not comprise the switching that heats and freeze in defrosting mode.
Below only just preferred embodiment of the present invention is described, but can not be interpreted as it is limiting the scope of the invention.The present invention is not only confined to above embodiment, and its concrete structure or shape allow to change.In a word, protection scope of the present invention should comprise those apparent conversion or alternative and remodeling to those skilled in the art.
