Abstract

The invention discloses a detection device and method for detecting installation head and an air-conditioning system control method. The detection device comprises an exhaust temperature sensor, an exhaust pressure sensor, a compressor detection system, an outlet pipe pressure sensor, an outlet pipe temperature sensor, an inlet pipe pressure sensor and a processor, wherein the exhaust temperature sensor is used for acquiring the exhaust temperature of a compressor, the exhaust pressure sensor is used for acquiring the exhaust pressure of the compressor, the compressor detection system is used for acquiring the running frequency and the suction intensity of the compressor, the outlet pipe pressure sensor is used for acquiring the outlet pipe liquid refrigerant pressure of an outdoor unit heat exchanger, the outlet pipe temperature sensor is used for acquiring the outlet pipe liquid refrigerant temperature of the outdoor unit heat exchanger, the inlet pipe pressure sensor is used for acquiring the inlet pipe refrigerant pressure of an indoor unit, and the processor is connected with the exhaust temperature sensor, the exhaust pressure sensor, the compressor detection system, the outlet pipe pressure sensor, the outlet pipe temperature sensor and the inlet pipe pressure sensor in a communicable manner. Therefore, the installation head between the indoor unit and an outdoor unit can be automatically calculated by the detection device for detecting the installation head.

Description

technical field [0001] The invention relates to the technical field of air conditioning, and more specifically, to a detection device and method for detecting installation drop and an air conditioning system control method. Background technique [0002] In the patent document with publication number CN104281762A, a type selection method of a multi-connected air conditioning system is disclosed, wherein the method involves the need to determine the drop correction coefficient of the indoor unit through the drop difference between the indoor unit and the outdoor unit . [0003] In the prior art, the height difference between the indoor unit and the outdoor unit is determined by manual height difference measurement. However, manually measuring the height difference between the indoor unit and the outdoor unit is not only time-consuming and laborious, but also causes large errors. [0004] Therefore, how to solve the disadvantages caused by manually measuring the indoor unit an...
