Table judges temperature range locating for current outdoor environment temperature T4 by being compared, determines the power output ratio of heater 3
Value.
If current environmental temperature T4 is -7 DEG C, 3 power of heater used tables look-up for 200W and knows that output power ratio is
40%, i.e., the power after heater 3 starts is 40% completely exported, i.e. 80W.Certainly for different type of machines, output power ratio
Parameter and environment temperature subregion section are different, no longer enumerate herein.
Step (3): detection condenser coil temperature T3, after air conditioner enters defrosting, condenser coil temperature T3 can be continuous
It increases, frost layer can be melted into water on condenser, can start to generate water vapour when increasing and being more than certain value, carry out condenser herein
Coil temperature T3 whether be more than preset value t1 (here, t1 takes 0 DEG C) judgement, do not meet such as, then follow the steps 4, such as meet, then
Execute step 5；
Step (4): control module remains off electric heater, and heater 3 does not start；
Step (5): control module starts heater 3 by output ratio, if current environmental temperature T4 is -7 DEG C, the hair of use
Hot 3 power of device is 200W, tables look-up and knows that output power ratio is 40%, i.e., the power after heater 3 starts is 80W, and is started
Execute step 6.
Step (6): detection condenser coil temperature T3, condenser coil temperature T3 will continue to constantly rise when air conditioner defrosts
Height, when increasing more than certain value, frost layer can all melt, and can quickly generate a large amount of water vapour, at this moment need to increase air-ducting ring
Calorific value on 2, herein carry out condenser coil temperature T3 whether be more than preset value t2 (here, t2 takes 10 DEG C) judgement, such as
It does not meet, thens follow the steps 7, such as meet, then follow the steps 8；
Step (7): control module is maintained the power of electric heater by original output ratio, as previously mentioned, as 80W,
Electric heater is then closed when air conditioner terminates defrost.
Step (8): control module promotes the output power ratio of heater 3 to highest 100%, such as the heater 3 used
Power is 200W, and 3 power output of heater at this time is 200W, and electric heater is then closed when air conditioner terminates defrost.
