Embodiment 1

[0063] Such as image 3 As shown, in the cooling mode, the outdoor unit 2 is equipped with a first pressure sensor 23 that detects the pressure value of the low-pressure side of the refrigerant, and the outdoor unit 2 performs cooling operation according to the received mode selection command control signal and power on / off command control signal.

[0064] And, if the indoor unit is started for the first time within the preset working cycle, the controller determines the target refrigerant saturation temperature Tes according to the current ambient temperature of the outdoor unit. For example, if the outdoor ambient temperature is between 30-35°C, the determined initial target The refrigerant saturation temperature is 6°C, the outdoor ambient temperature is between 35-40°C, the initial target refrigerant saturation temperature is 3°C, the outdoor ambient temperature is between 25-30°C, and the initial target refrigerant saturation temperature is 8°C . If the indoor unit is no...

Embodiment 2

[0071] Such as Figure 4 As shown, in the heating mode, the outdoor unit 2 is equipped with a second pressure sensor 24 that detects the pressure value of the high-pressure side of the refrigerant, and the outdoor unit 2 operates according to the received mode selection instruction control signal and switch instruction control signal. .

[0072] And, if the indoor unit is started for the first time within the preset working cycle, the controller determines the target refrigerant saturation temperature Tcs according to the current ambient temperature of the outdoor unit. For example, if the outdoor ambient temperature is between 7-10°C, the determined initial target The refrigerant saturation temperature is 46°C. If the indoor unit is not started for the first time within the preset working cycle, the controller uses the target refrigerant saturation temperature recorded at the last shutdown as the initial target refrigerant saturation temperature for this startup.

Abstract

The invention discloses a control method of the air conditioner system. The control method comprises the following steps of obtaining a work mode of the air conditioner system, and according to the work mode, starting an inverter compressor of the outdoor unit of the air conditioner system; obtaining a target refrigerant saturation temperature; according to the target refrigerant saturation temperature, frequency converting control over the inverter compressor is carried out; in the process of carrying out frequency converting control over the inverter compressor, obtaining operating time and the operating frequency or operating current of the inverter compressor; and according to the operating time and the operating frequency or operating current of the inverter compressor, adjusting the target refrigerant saturation temperature. According to the control method of the air conditioner system, the air conditioner system can be independent of the outdoor unit so as to carry out frequency converting control over the inverter compressor of the outdoor unit, a process of controlling parameter transmission is reduced, the complexity of the air conditioner system is reduced, and operating reliability of the air conditioner system is improved. The invention further discloses the outdoor unit of the air conditioner and the air conditioner system with the outdoor unit.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air conditioning system control method, an outdoor unit of the air conditioning system, and an air conditioning system with the outdoor unit. Background technique [0002] With the continuous development of air conditioning technology, DC inverter air conditioners are becoming more and more popular in the market, and their sales are also increasing rapidly. At present, the frequency conversion air conditioners on the market all need to be installed together, and the indoor unit and the outdoor unit need special supporting communication methods to realize the control of the compressor of the outdoor unit. Therefore, the installation of indoor and outdoor units must be synchronized and matched. [0003] The structure of the existing inverter air conditioning system is as follows: Figure 1A As shown, the outdoor unit must receive a series of signals from the indoor uni...
