Embodiment 1

[0127] After starting and running for 5 minutes in the cooling mode of the air conditioner, the parameter acquisition module acquires the operating frequency of the compressor 1 and the temperature T2B of the indoor heat exchanger in the indoor heat exchanger 4 as operating parameters, and the corresponding refrigeration first preset parameter threshold is the operating frequency of the compressor 20Hz, the temperature of the indoor heat exchanger is 3°C, and the buffer time is set to 2 minutes; the corresponding second preset parameter threshold for cooling is that the temperature of the indoor heat exchanger is 15°C.

[0128] When the operating frequency of the compressor 1 is <20 Hz and T2B<3° C. for 2 minutes, the controller determines that the air conditioner compressor 1 is in a state of excessive energy output, and turns on the solenoid valve 62 .

[0129] After the solenoid valve 62 is turned on, within 2 minutes, if the operating frequency of the compressor 1 is >20Hz ...

Embodiment 2

[0131] The air-conditioning heating mode starts and runs for 5 minutes, and the parameter acquisition module acquires the temperature T2B of the indoor heat exchanger 4 in the indoor heat exchanger 4 as an operating parameter, and the corresponding threshold of the first preset parameter for heating is the temperature of the indoor heat The thermal second preset parameter threshold is the indoor heat exchanger temperature of 48°C, and the buffer time is set to 2 minutes.

[0132] When the indoor heat exchanger temperature T2B>51°C for 2 minutes, it is judged that the energy output of the air conditioner compressor 1 is excessive, and the controller opens the electronic expansion valve 61;

[0133] After the electronic expansion valve 61 is opened, if the indoor heat exchanger temperature T2B<48°C lasts for 2 minutes, the controller judges that the energy output of the air conditioner compressor 1 returns to normal, and closes the electronic expansion valve 61 .

Embodiment 3

[0135] The air-conditioning heating mode starts and runs for 5 minutes, and the parameter acquisition module acquires the pressure Pc of the refrigerant passing through the outdoor heat exchanger in the outdoor heat exchanger 3 as an operating parameter, and the corresponding heating first preset parameter threshold is the refrigerant passing through the outdoor heat exchanger The pressure critical value is 3.3MPa, the second preset parameter threshold for heating is 3.1MPa for the refrigerant pressure passing through the outdoor heat exchanger, and the buffer time is set to 2 minutes.

[0136] When the refrigerant pressure Pc>3.3MPa through the outdoor heat exchanger lasts for 2 minutes, the controller judges that the energy output of the air conditioner compressor 1 is excessive, and opens the electronic expansion valve 61;

[0137] After opening the electronic expansion valve 61, if the pressure of the refrigerant passing through the outdoor heat exchanger Pc<3.1MPa lasts fo...

Abstract

The invention discloses an air conditioner energy output regulating method and an air conditioner. The air conditioner comprises a compressor, a four-way valve, a gas-liquid separator, an outdoor heat exchanger, an indoor heat exchanger, a shunt loop and a controller. One end of the shunt loop is connected between the output end of the compressor and the input end of the four-way valve, and the other end of the shunt loop is connected between the backflow end of the four-way valve and the input end of the compressor. The controller is used for controlling the shunt loop to be electrified or closed. The air conditioner energy output regulating method comprises the following steps that whether energy output of the compressor during operation of the air conditioner is excessive or not is judged by the controller; and if the energy output of the compressor is excessive, the shunt loop is electrified by the controller until the energy output of the compressor returns to normal. According to the air conditioner energy output regulating method and the air conditioner, electrification and closure of the shunt loop can be automatically controlled according to the actual working state of the air conditioner, and excessively output coolants are timely shunted, so that the technical problems that the service life is shortened and the reliability is reduced due to overclock operation of the compressor are solved.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to an air conditioner energy output adjustment method and an air conditioner. Background technique [0002] In general air conditioning systems, the energy output of compressors in some air conditioners cannot be reduced due to adjustment restrictions. When the actual cooling capacity or heat required by the environment is low, the energy output of the compressors is too large, and the compressors with excessive output are overclocked, resulting in The energy consumption of the air conditioner increases, and at the same time, the long-term overclocking operation reduces the service life and reliability of the compressor. Contents of the invention [0003] The main purpose of the present invention is to provide a method for adjusting the energy output of an air conditioner and an air conditioner, aiming at solving the problem that the energy consumption of the air conditioner increa...
