Reverse cycle air-conditioning and refrigeration training equipment

Reverse cycle air-conditioning and refrigeration training equipment. First, the device: 1, this equipment through a compressor driven two vapor compression refrigeration cycle circuit in which a circuit is used in forced air-cooled condenser, and the other uses a water-cooled condenser can be controlled Similarities and Differences condenser pressure under the premise of comparing two ways of condensate. 2, when using air-cooled condensers, four-way valve can be used to defrost the condenser (reverse circulation). 3, the device offers four different types of throttling expansion valve, can compare their performance. Second, the device features: 1, the system comprises two condensers are: air-cooled condenser and a water-cooled condenser. 2, forced air and static evaporator has a dual temperature control. 3. Optional accessories: experiments with student kits, experimental testing and maintenance tools. 4, to provide experimental operating instructions and the like. 5, can demonstrate common cooling failure.
