The present application relates to a
heat pump control method, device, air conditioner and computer-readable medium. The method includes: pre-judging unit faults based on
water capacity data and anti-freeze protection data; if there is no fault, controlling the start and stop of each unit module based on the user
demand load and the preset module
start time; if there is a fault, determining the
heat pump control sequence based on the number of anti-freeze protection times and the fault type; if entering the
water capacity insufficient control sequence, determining the first extension time according to the
water capacity data, controlling the compressor operation based on the first extension time and the preset compressor
start time and giving an early warning; if entering the anti-freeze protection control sequence, determining the second extension time according to the anti-freeze protection data, controlling the compressor operation based on the second extension time and the preset compressor
start time and giving an early warning. The present application can reduce the frequent start and stop of the unit, improve the reliability and stability of the
system, and solve the problems of frequent start and stop of the unit, poor reliability and stability in the prior art.
