Novel hybrid refrigeration cycle system

Abstract

The invention discloses a novel hybrid refrigeration cycle system. The novel hybrid refrigeration cycle system comprises an evaporator, an output end of the evaporator is divided into two branches, one branch is connected with an input end of a compressor while the other branch is connected with an input end of a booster, an output end of the compressor is connected with an input end of a condenser A, an output end of the condenser A is connected with an input end of the evaporator, an output end of the booster is connected with a secondary flow inlet of an ejector, and an output end of the ejector is connected with an input end of a condenser B. An output end of the condenser B is divided into two branches, one branch is connected with the input end of the evaporator, and the other branch sequentially passes through a pump and a generator to be connected with a primary flow inlet of the ejector. Compression type refrigeration cycle and ejection type refrigeration cycle of a traditional automobile air conditioner are in parallel operation to share one evaporator, a novel hybrid refrigeration cycle way is provided to take advantages of the ejection type refrigeration technology, and the problems caused by single use of a traditional ejector are solved by adoption of the compressor.

Description

technical field [0001] The invention relates to a mixed refrigerating cycle system, in particular to a compression / jet mixed refrigerating system used for refrigeration in automobiles, ships and the like. Background technique [0002] As the number of automobiles in our country increases year by year, the proportion of automobile energy consumption in the total energy consumption is also increasing. At present, the automobile air conditioner adopts the vapor compression refrigeration working method, which consumes part of the engine power to obtain the cooling capacity, so that the engine output power increases by 10%-12% compared with that without the air-conditioning system, and the fuel consumption of the automobile will also increase by 14%- 20%, and at the same time lead to uneven load of various parts of the engine and increase of vehicle exhaust emissions, which will aggravate air pollution. [0003] The ejector is introduced into the steam injection cycle due to its...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the deficiencies in the prior art, the present invention discloses a novel hybrid refrigeration cycle system and method. The present invention proposes a compression / jet hybrid refrigeration cycle, the purpose of which is to make full use of the energy generated during the operation of automobiles or ships Waste heat drives its air conditioner, and at the same time overcomes the traditional compressor refrigeration method, which consumes extra energy for compressor work, reduces the energy efficiency loss of the system, and the low energy utilization rate of the ejector refrigeration method.
