Abstract

The invention provides a control method and system and an air conditioner. The method is used for controlling the frequency of a compressor during heating operation of a VRF (variable refrigerant flow) air conditioning system, and the method comprises the following steps: acquiring a critical environment temperature corresponding to preset evaporation pressure of the VRF air conditioning system; detecting the outdoor environment temperature; judging whether the outdoor environment temperature is greater than the critical environment temperature; if the outdoor environment temperature is lowerthan the critical environment temperature, obtaining actual evaporation temperature of the VRF air conditioning system heating mode, and adjusting the frequency of the compressor according to the actual evaporation temperature and the preset target evaporation temperature; and under the condition that the outdoor environment temperature is larger than the critical environment temperature, obtaining the actual condensation temperature of the VRF air conditioning system heating mode, and adjusting the frequency of the compressor according to the actual condensation temperature and the preset target condensation temperature. According to the method, the cost is greatly saved, the product market competitiveness is improved, compared with previous control, system operation parameters are closerto design values, and the system operation efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of air conditioning, in particular, to a control method, system and air conditioner. Background technique [0002] At present, in the related technology, when the multi-connected mechanism is running in heat, the frequency of the compressor is controlled according to the target discharge pressure. When the detected evaporation pressure is greater than the target suction pressure, in order to ensure the reliability of the compressor, the compressor frequency is controlled according to the target suction pressure. Air pressure is controlled. This control method needs to install a high-pressure sensor in the exhaust pipe of the multi-connected air-conditioning system to detect the exhaust pressure (P d ), install a low-pressure sensor on the compressor suction pipe to detect the suction pressure (P s ). [0003] Since the compressor row and suction pipe need to be installed with high and low pressure...
