Abstract

The invention discloses a refrigeration device. The refrigeration device comprises a compressor assembly, an outdoor heat exchanger, an indoor heat exchanger and a flash vessel, wherein a refrigerant circulation flow path is formed by the compressor assembly, the outdoor heat exchange, the indoor heat exchanger and the flash vessel. The compressor assembly comprises a first cylinder and a second cylinder. The first cylinder is provided with a first gas suction passageway. The second cylinder is provided with a second gas suction passageway. The flash vessel is provided with a first connector, a second connector and a gas connector. A first throttling element is connected between the first connector and the outdoor heat exchanger in series. A second throttling element is connected between the second connector and the indoor heat exchanger in series. The gas connector is connected with the second gas suction passageway. One of the indoor heat exchanger and the outdoor heat exchanger is an evaporator, and the other one of the indoor heat exchanger and the outdoor heat exchanger is a condenser. The evaporator communicates with the first gas suction passageway. By means of the refrigeration device, performance of the refrigeration device itself can be improved, it can also be avoided that the second cylinder of the compressor assembly is damaged by long-time liquid impact, and reliability of work of the compressor assembly is ensured.

Description

technical field [0001] The invention relates to the refrigeration field, in particular to a refrigeration device. Background technique [0002] In the related art, the refrigeration system using the flash evaporator can separate the throttling gaseous refrigerant (this part of the gaseous refrigerant does not participate in heat exchange even if it passes through the heat exchanger, but occupies the space of the heat exchanger), and the gaseous refrigerant no longer Instead of going through the heat exchanger, it returns directly to the second cylinder of the compressor assembly, which reduces the pressure loss of the refrigeration system and improves the efficiency of the heat exchanger. When the flash evaporator is installed in the refrigeration system of the related art, not only the performance of the refrigeration device cannot be improved, but also the second cylinder of the compressor assembly will be damaged due to liquid hammer for a long time, which affects the rel...
