Problems solved by technology

However, the existing multi-connected air-conditioning systems are all single-stage compression refrigeration systems, which are only applicable to the field of air-conditioning
For multi-temperature cold storage, multi-temperature refrigerated trucks, etc., when a single-stage compression refrigeration system (usually used in high-temperature refrigeration environments) and a two-stage compression refrigeration system (usually used in low-temperature refrigeration environments) coexist, high and low-temperature refrigeration systems need to be The refrigeration system is independently configured in the environment, but they cannot be switched between each other, resulting in a waste of refrigeration device configuration. There is still a technical gap for multi-lines that can be used in single-stage and double-stage compression refrigeration cycles.

Abstract

The invention discloses a two-stage multi-unit single-throttling incomplete-intercooling refrigeration system, and provides the refrigeration system which utilizes valve switching to realize single-stage compression and two-stage compression circulation. The refrigeration system comprises a first air intake pipeline, a second air intake pipeline, a high pressure liquid supply pipeline, a first evaporator, a second evaporator, a first throttling device, a second throttling device and a plurality of double-compressor units, wherein each double-compressor unit comprises a first compressor, a second compressor, a first valve, a second valve, a third valve, a fourth valve, a fifth valve, a sixth valve, a condenser, a third throttling device and an inter-cooler. The refrigeration system consists of a plurality of double-compressor units connected in parallel to the first air intake pipeline, the second air intake pipeline and the high pressure liquid supply pipeline, and single-stage compression and two-stage compression are realized through the opening or closing of the internal valves, and each compressor in the double-compressor unit can be used individually. The system is small in one-time investment, and flexible in adjustment, and the temperature fluctuation in a refrigerated warehouse is small.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a two-stage multi-connection one-throttle refrigeration system with incomplete cooling in the middle. Background technique [0002] The multi-connected air conditioning system composed of multiple outdoor units and multiple indoor units is widely used in the field of air conditioning because of its flexible operation, high energy efficiency ratio, and easy control. However, the existing multi-connected air-conditioning systems are all single-stage compression refrigeration systems, which are only applicable to the air-conditioning field. For multi-temperature cold storage, multi-temperature refrigerated trucks, etc., when a single-stage compression refrigeration system (usually used in high-temperature refrigeration environments) and a two-stage compression refrigeration system (usually used in low-temperature refrigeration environments) coexist, high and low-temperature re...
