Trouble and maintenance of electronic expansion valve and four-way valve

What is chilled water air conditioning system II

Central air-conditioning is no stranger to us. We often think that central air-conditioning is a Freon system, which uses Freon as a medium for refrigeration

Compare the performance of three commonly used refrigeration compressors, and clearly understand the outdoor unit
