Compressor performance detection device, air conditioning system with the device and control method

Abstract

The invention relates to a compressor performance detection device, which includes a compressor (1), an outdoor heat exchanger (2), and an indoor heat exchanger (3), and also includes an exhaust pipe temperature sensing package ( 4), the outdoor environment temperature-sensing package (5) for detecting the outdoor environment temperature, the indoor environment temperature-sensing package (6) for detecting the indoor environment temperature, and the first detection device for detecting the low-pressure saturation temperature Te of the air-conditioning system and the second detection device for detecting the high-pressure saturation temperature Td of the air-conditioning system, according to the compressor performance detection device of the present invention, it is possible to timely and accurately determine whether the compressor is dirty and blocked at the suction port, thereby timely and accurately Judging whether the operation of the compressor is abnormal can achieve the effect of accurately detecting the performance of the compressor, and can also provide accurate and effective judgment conditions for the subsequent stage to perform corresponding operations based on the detection results. The invention also relates to an air conditioning system and a control method provided with the device.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to a compressor performance detection device, an air conditioning system with the device and a control method. Background technique [0002] In the existing multi-connected air conditioning system, when the compressor suction port is dirty and blocked, it is rare to judge the specific fault in time and give a timely pre-alarm and / or remind the customer. Generally, it is only discovered after the compressor has been damaged, or It is simply to detect the discharge temperature of the compressor to judge whether the system is abnormal. However, such a detection method cannot determine whether the refrigerant in the system is reduced or the suction port of the compressor is dirty and blocked. [0003] Since the above-mentioned existing air-conditioning system cannot accurately detect whether the air inlet of the compressor is dirty and blocked, and thus cannot accu...
