Abstract
The utility model provides an internal-switching water source type heat pump air-conditioning unit, which comprises a closed refrigerant loop. The loop is composed of a compressor, a four-way valve, two heat exchangers, two expansion valves, two solenoid valves and two one-way valves. The two heat exchangers are connected with the two ends of the compressor through the four-way valve. The two expansion valves and the two one-way valves are connected in parallel with each other between the two heat exchangers. The two one-way valves are opposite to each other in direction. Arranged between the two one-way valves, a solenoid valve, a liquid lens, a drying filter and a high-pressure reservoir are connected in series with the two one-way valves to be connected between the two expansion valves. The internal-switching water source type heat pump air-conditioning unit has the advantages of simple pipeline configuration, convenient design and quick construction. Meanwhile, two systems are effectively free of the water leakage phenomenon.
