The invention discloses an air-conditioning system and a method for judging the length of a connecting pipe of an indoor unit and an outdoor unit. The method for judging the length of the connecting pipe of the indoor unit and the outdoor unit in the air-conditioning system comprises: detecting the inlet temperature of an evaporator; detecting the saturation temperature corresponding to the inlet pressure of a compressor; and judging the length of the connecting pipe of the indoor unit and the outdoor unit in the air-conditioning system according to the difference between the inlet temperature of the evaporator and the saturation temperature corresponding to the inlet pressure of the compressor, wherein the corresponding relationship between the temperature difference and the length of the connecting pipe of the indoor unit and the outdoor unit is pre-stored in the air-conditioning system, and the length of the connecting pipe of the indoor unit and the outdoor unit can be measured through measuring the temperature difference. Therefore, the length of the connecting pipe of the indoor unit and the outdoor unit of the air-conditioning system can be measured conveniently.
Description
technical field [0001] The invention relates to the field of air conditioning, in particular to an air conditioning system and a method for judging the length of connecting pipes of indoor and outdoor units thereof. Background technique [0002] Usually, the direct evaporative refrigeration and air-conditioning system consists of an outdoor unit and an indoor unit connected by connecting pipes. Due to the limitation of the installation site conditions of the air conditioning unit, the length of the connecting pipeline is uncertain. The length of the connecting pipe affects the amount of refrigerant injected. At the same time, the resistance loss caused by the refrigerant flowing through the connecting pipe will reduce the cooling capacity of the air conditioning unit. The longer the connecting pipeline, the greater the resistance loss and the greater the drop in refrigeration capacity. Especially for the variable refrigerant flow system (VRF), after the cooling capacity dr...
