Detection methodsOutdoor heat exchanger temperature sensor, timer.
Explanation of operation1) At the deice starting signal, the compressor frequency is set to the value as previously mentioned.2) At 120 sec. after deice starting signal generated, 4 way valve OFF and at the same time outdoor fan is OFF, indoor fan is OFF,compressor frequency is set to the previously mentioned value.3) WIthin 30 sec. after the 4 way valve OFF, the compressor frequency is set to the previously mentioned value.4) If the outdoor heat exchanger temperature is above a°C, the compressor frequency is set to the value as previously mentioned.5) After the compressor frequency is changed according to the item 4), in case either outdoor heat exchanger temperature more than b°Cor 10.5 minutes lapsed after 4 way valve OFF is fulfilled, 30 sec. calculation start.6) After 5) operated, if the outdoor heat exchanger temperature is more than c°C or 30 sec. lapsed, deice operation completion signaltransmit, the compressor frequency is set to the previously mentioned value. And timingly ON signal transmit on outdoor FM.7) After 59 sec. lapsed after deice operation completion signal generated, 4 way valve/indoor fan is ON, compressor frequency becomeFREE, and recover to normal heating operation.
Deice operation judgement conditionWhen any of below a, b, c, d condition is satisfied, deice signal is produced.a. Continuously, outdoor heat exchanger temperature < 3°C for 120 minutes and outdoor heat exchanger temperature< -6°C for 3 minutes and outdoor air temperature > -1°C and Comp. is ON.b. Continuously, outdoor heat exchanger temperature < 3°C for 80 minutes and outdoor heat exchanger temperature< -7°C for 3 minutes and outdoor air temperature > -1°C and Comp. is ON.c. Continuously, outdoor heat exchanger temperature < 3°C for 40 minutes and outdoor heat exchanger temperature< -9°C for 3 minutes and outdoor air temperature -3°C and Comp. is ON.d. Continuously, outdoor heat exchanger temperature < 3°C for 40 minutes and outdoor heat exchanger temperature< -11°C for 3 minutes and outdoor air temperature < -3°C and Comp. is ON.However, the first deice will start only after minimum of 60 minutes in operation.(2nd deice and onward shall follow above conditions)
Hej,jag har en E12 EKEB, vet du om det är samma parametrar för den? Vilka är a,b,c temp? Om det är fasta tidsintervall på avfrostningen, tar dem då lika lång tid också? Har någon koll på hur lång tid det ska ta från det att fläkten på innerdelen stängs av tills dess att den sätts på igen? Ska det ta 5 min?
