Abstract
The invention belongs to a kind of unit compression refrigeration equipment, be suitable for miniature cold storage.Comprise compressor, condensation liquid reservoir, regenerator, expansion valve, evaporimeter, characteristics are need not the water cooling working medium, thereby energy-conservation.It is simple in structure, is convenient to the miniature cold storage transformation.
Description
The invention belongs to refrigeration plant, especially a kind of unit compression refrigeration equipment is applicable to miniature cold storage.
The refrigeration plant condensation portion of existing miniature cold storage all adopts water-cooled because cooling water is not a recirculated water, with after pour off in vain, cause seriously expending of water.For this reason, once imagination is built cooling tower so that cooling water can recycle.But this is to lose more than gain for miniature cold storage, because the electric energy of many like this consumptions will exceed the amount of expending of water.So still do not propose the energy-conservation good method of miniature cold storage so far.
Purpose of the present invention just is to propose a kind of unit compression refrigeration equipment that is suitable for miniature cold storage, and it saves the energy, and is simple.
The object of the present invention is achieved like this: it comprises compressor, condensation liquid reservoir, regenerator, expansion valve I, the evaporimeter of forming cooling cycle system, it is characterized in that: the input of condensation liquid reservoir cooling pipe is connected to the expansion valve II, this expansion valve II other end communicates with connecting line between expansion valve I and regenerator, and the pipeline of the output of said cooling line and compressor low-pressure end and evaporimeter output intersects at regenerator.This feature makes the condensation liquid reservoir in fact also become an evaporimeter, cools off the working medium that needs condensation so lean on the evaporation of working medium to absorb heat, and need not use water cooling.
Further specify structure of the present invention and operation principle below in conjunction with example.
Fig. 1 is a kind of structural principle schematic diagram of the present invention.
According to Fig. 1, the present invention includes compressor 1, air-cooled condenser 2, condensation liquid reservoir 3, regenerator 6, expansion valve 5,8, evaporimeter 7, couple together by pipeline, form two cooling cycle systems.A system is directly used in freezer refrigerating, and the working medium cyclic process is: compressor 1 → air-cooled condenser 2 → condensation liquid reservoir 3 → regenerator 6 → expansion valve 8 → evaporimeter 7 → regenerator 6 → compressor 1.Another system is used for the working medium of 3 li of cooling condensation liquid reservoirs, the cyclic process of working medium is: compressor 1 → air-cooled condenser 2 → condensation liquid reservoir 3 → regenerator 6 → expansion valve 5 → cooling pipe 4(is in this evaporation heat absorption) → regenerator 6(mixes in working medium of this and evaporimeter 7 outputs) → compressor 1, because this system is arranged, condensation liquid reservoir 3 just need not adopt water-cooled, and cooling effect has clear improvement, adopt air-cooled condenser 2 also can reach better cooling effect (according to test, cryogenic temperature reaches-20 ℃) again.
It is energy-conservation, simple that the present invention has, and is convenient to transform the advantages such as miniature cold storage.
