Besides, the quantity of cooling medium is also ensured.
Description
Technical field
The present invention relates to a kind of air-conditioner operation method.Particularly relate to a kind of method for controlling defrosting operation of air conditioner that can guarantee the air-conditioner defrost performance with induction heater.
Background technology
Usually air-conditioner is made up of heater, refrigeration machine, clarifier etc., can or purify for room air refrigeration or heating, for the user creates suitable indoor environment.
If classification substantially, air-conditioner can be divided into Saperated air conditioner and integral air conditioner.Separation type and integral air conditioner have identical function.Saperated air conditioner is provided with the indoor set with cooling/heat release in the indoor, the off-premises station with heat release/cooling and compressor is set in the outside, and links off-premises station and indoor set with the refrigerant pipe.Be arranged on and be provided with condenser (outdoor heat converter) and compressor in the outdoor off-premises station, be arranged in the indoor indoor set, be provided with evaporimeter (indoor heat converter).
As shown in Figure 1, for Saperated air conditioner, off-premises station includes the front of formation housing and header board 1, fan 2, fan electromotor 3, condenser 4, the back that constitutes housing and the back plate 5 of both sides of end face substantially, constitutes base plate 6, compressor 7 and the refrigerant communication port 8 of housing bottom surface.
As shown in Figure 2, when air-conditioning carries out cooling operation, refrigerant flow to be by compressor 7 to condenser 4, flow to evaporimeter 10 by condenser 4 by choke valve 9 again, return compressor 7 again from evaporimeter 10.When heating running, it is the flow direction opposite with refrigeration that refrigerant flows to, and, to evaporimeter 10, flows to condenser 4 by evaporimeter 10 by choke valve 9 by compressor 7 more that is, turns back to compressor 10 again from condenser 4.
Above-mentioned air-conditioning is in heating process, and frosting is understood on the surface of condenser, and the frost of being tied has hindered the heat exchange performance of condenser.Therefore, after condenser has been tied frost to a certain degree, master control program will be carried out operation defrosting program.At present, what the Defrost mode of air-conditioning mostly adopted is, shuts down the back and earlier cross valve is closed, and cross valve is commutated to the refrigerating operaton state, and the running refrigerating pattern defrosts, and the blower fan of indoor and outdoor machine is out of service simultaneously, and in defrost process, air-conditioning stops heating operation.Owing to stop heating operation, directly influenced the heating effect of air-conditioning, and the cycle of defrosting is also longer.
In order to overcome the problem that air-conditioner defrosting must be shut down, also developed the air-conditioner of not shutting down defrosting now.As number of patent application is 200810153761.5, and name is called disclosed a kind of compound Defrost mode in the patent application of " a kind of hot gas of air-conditioner be close to logical continuous heat-supply and defrost loop structure ".Be to be close to road all at hot gas of the other increase of compressor, the hot gas near valve is arranged on this path.Specifically be, the outlet of compressor is close to all with hot gas, and the import on road is connected, hot gas is close to all, and the road other end divides two-way by the hot gas near valve again, one the tunnel through the import of capillary to evaporimeter, the import of compressor is arrived through capillary in another road, and on the fluid reservoir of compressor induction heater is set.
But above-mentioned compound Defrost mode is not controlled the induction heater on the fluid reservoir, is easy to cause bad consequence.As, producing overload, Yin Wendu is too high and produce fire, or Yin Wendu is too high that refrigerant in the fluid reservoir is decomposed, and influences the refrigeration or the heating effect of air-conditioner.
Summary of the invention
Technical problem to be solved by this invention is that a kind of method for controlling defrosting operation of air conditioner with induction heater that can guarantee the air-conditioner defrost performance is provided.
The technical solution adopted in the present invention is: a kind of method for controlling defrosting operation of air conditioner with induction heater comprises the steps:
1) master control program of operation compressor is opened induction heater simultaneously;
2) after induction heater ran to first setting-up time, whether the variable quantity of judging input current was to return master control program after then starting four-way valve defrosting, otherwise enters the 3rd step less than the variable quantity of setting;
3) judge whether induction heater runs to second setting-up time, be then to enter the 4th step, otherwise continue to judge whether induction heater runs to the time of setting;
4) judging the temperature whether the fluid reservoir temperature has risen and set, is not to enter the 5th step, is then enter the 6th step;
5) induction heater is set to underdrive operating, returns master control program after operation is finished;
6) judge that the fluid reservoir temperature whether greater than first design temperature of fluid reservoir, is to enter the 7th step, otherwise enters the 8th step;
7) induction heater is set to low-low operation, operation back continues to judge that the fluid reservoir temperature is whether greater than second design temperature of fluid reservoir, be to restart again after then induction heater cutting out time of setting, returning the 2nd step simultaneously circulates again, otherwise, keep low-low Defrost operation state, return master control program after the end;
8) whether the temperature of judging the fin in the master board is then to enter the 9th step greater than first design temperature of disconnected fin, otherwise keeps existing Defrost operation state, returns master control program after the end;
9) induction heater is set to low-low operation, whether the temperature that fin is continued to judge in operation back is greater than the temperature of second setting of the fin that breaks, be to restart again after then induction heater cutting out time of setting, returning the 2nd step simultaneously circulates again, otherwise, keep low-low Defrost operation state, return master control program after the end.
First setting-up time of the described induction heater operation of the 2nd step was 5 seconds, and the variable quantity of setting electric current is 1A.
Second setting-up time of the described induction heater operation of the 3rd step is 2 minutes.
The ascending temperature that the described fluid reservoir of the 4th step is set is 20 ℃.
First design temperature of the described fluid reservoir of the 6th step is 120 ℃.
Second design temperature of the described fluid reservoir of the 7th step is 140 ℃.
First design temperature of the described fin of the 8th step is 70 ℃.
Second design temperature of the described fin of the 9th step is 80 ℃.
