Water-cooled type low-temperature refrigerant compressor unit with economizer and silencer

Abstract

The invention relates to relates to a thermodynamic cycle device, in particular to a water-cooled type low-temperature refrigerant compressor unit with an economizer and a silencer. The water-cooled type low-temperature refrigerant compressor unit comprises a compressor (1), a condenser (2), an expansion valve A (3) and an evaporator (4). An exhaust outlet (1-2) is sequentially connected with the condenser (2), the expansion valve A (3), the evaporator (4) and an air sucking inlet (1-1), and the economizer (5), the silencer (6), an expansion valve A (7) and a magnetic valve (8) are arranged among the condenser (2), the expansion valve A (3) and an economizer connecting standby port (1-3). An outlet of the condenser (2) is respectively connected with the magnetic valve (8) and a first inlet (5-1), and the magnetic valve (8) is connected with a second inlet (5-2) through the expansion valve B (7). A second outlet (5-4) is connected with the economizer connecting standby port (1-3) through the silencer (6). The water-cooled type low-temperature refrigerant compressor unit has the advantages of being high in energy efficiency and safety.

Description

technical field [0001] The invention relates to a thermodynamic cycle device, in particular to a water-cooled low-temperature refrigeration compressor unit with an economizer and a muffler which utilizes a refrigeration compressor to realize a thermodynamic cycle. Background technique [0002] Chinese Patent Publication No. CN101089518A discloses an air-cooled water-cooled double evaporator hot water unit, which has a refrigeration cycle circuit composed of a compressor, a water-cooled condenser, an air-cooled evaporator, and a water-cooled evaporator. There is a controller, and the compressor is connected to a water-cooled condenser through a four-way valve. The water-cooled condenser is connected with an inlet and an outlet, and the water-cooled condenser is connected to a thermal expansion valve. The air-cooled evaporator and the water-cooled evaporator are provided with water inlet and outlet ports, the water-cooled evaporator and the air-cooled evaporator are connected...

Its main shortcomings: high energy consumption, general efficiency

[0005] Since the refrigerant gas passes through the suction and exhaust ports periodically at high speed, the compressor makes a lot of noise, and at the same time, it will cause vibrations in the pipeline connected to the compressor, which often leads to pipeline breakage and leakage.
