Abstract
The utility model relates to a three-in-one refrigeration device which is composed of a liquid reservoir 1 connected with a pipeline, a gas-liquid segregator, a heat exchanger, a condenser 3, a compressor 4, an evaporator 5 and a thermostatic expansion valve 6. The utility model is characterized in that the gas-liquid segregator and the heat exchanger are integrated, forming a gas-liquid segregator and heat exchanger 2; the periphery of the gas-liquid segregator and heat exchanger 2 is provided with the liquid reservoir 1. The utility model has the advantages of small volume, high efficiency and safe operation.
Description
(1) technical field: the utility model relates to a kind of refrigerating plant that is used for the hypothermic saline unit, especially a kind of gas-liquid separator, heat exchanger and liquid reservoir three-in-one refrigerating plant together.
(2) background technology: in refrigeration system, the effect of liquid reservoir 1 is the refrigerant liquid of storage system and regulates the liquid supply rate that produces because of load variations.The effect of gas-liquid separator is that the fluid separation applications in the cold-producing medium that will be drawn back by evaporimeter 5 is come out to prevent that too much liquid from being produced liquid hammer by compressor 4 suction, the liquid of separating contains working medium and lubricating oil, return compressor 4 continuously uniformly by the aperture on the escape pipe, to guarantee returning of lubricating oil, it can also further cool off the refrigerant liquid that is come out by condenser 3 in addition, make it pass through to be single liquid before the heating power expansion valve 6, increase specific refrigerating effect on the one hand, improve the operating efficiency of heating power expansion valve 6 on the other hand.At present, the gas-liquid separator, heat exchanger and the liquid reservoir that are used for the refrigerating plant of hypothermic saline unit separate, with its independently form be connected in the pipeline, the refrigerating plant volume of this structure is bigger, the pipeline complexity, thus the high-pressure liquid line resistance increased, increase energy consumption.What particularly point out is in the hypothermic saline unit, general evaporating temperature is smaller or equal to negative 30 degree, oil of in gas-liquid separator, separating and liquid working substance generation lamination, oil is on the upper strata, working medium is in lower floor, and after working medium was drawn back compressor, the oil-enriched layer of thickness settled down and may stop up back the liquid aperture, cause the operation of compressor oil starvation, often therefore burn machine.
(3) summary of the invention: the purpose of this utility model is to overcome the deficiency of above-mentioned prior art, and provide a kind of volume little, can prevent the obstruction of hole for back flow effectively, improve the reliability of unit operation, improve working medium Unit Weight enthalpy difference, can increase the three-in-one refrigerating plant of the refrigerating capacity of whole system.
The purpose of this utility model can reach by following measure: three-in-one refrigerating plant, the liquid reservoir 1 that it is connected by pipeline, gas-liquid separator and heat exchanger, condenser 3, compressor 4, evaporimeter 5, heating power expansion valve 6 is formed, it is characterized in that: gas-liquid separator and heat exchanger unite two into one and are the gas-liquid separator heat exchanger 2 of holding concurrently, and are provided with liquid reservoir 1 in the hold concurrently periphery of heat exchanger 2 of gas-liquid separator.
Compared with the prior art the utility model has following good effect: owing to taked the organic combination of gas-liquid separator, heat exchanger, liquid reservoir 1 three devices, make the smaller volume of refrigerating plant; Can make and get back to the hold concurrently high-temp liquid that in evaporimeter 5, does not have fully evaporation and overheated cold-producing medium to cool off in the liquid reservoir 1 of heat exchanger 2 of gas-liquid separator and make it cold excessively, improve working medium Unit Weight enthalpy difference, thereby increased the refrigerating capacity of whole system; In three-in-one refrigerating plant, when oil of in gas-liquid separator is held concurrently heat exchanger 2, separating and liquid working substance generation lamination, oil is on the upper strata, and working medium is in lower floor, after working medium is drawn back compressor, the oil-enriched layer of thickness settles down by the liquid of relatively-high temperature in the liquid reservoir, be generally 40 ℃, it is heated incessantly, the viscosity of oil-enriched layer is diminished, can prevent the obstruction of hole for back flow effectively, improve the reliability of unit operation.
(4) description of drawings: accompanying drawing is the flowage structure schematic diagram of three-in-one refrigerating plant.
(5) specific embodiment: the high-temperature high-pressure refrigerant steam of being discharged by compressor 4 enters condenser 3 to carry out exchange heat with cooling water and liquefies, the heat water that is cooled is taken away, become highly pressurised liquid and enter liquid reservoir 1, by gas-liquid separator hold concurrently in the heat exchanger 2 fully evaporation and overheated cold-producing medium do not cool off in evaporimeter, make it become subcooled liquid, filter through filter, in the refrigerant liquid inflow evaporator 5 of heating power expansion valve 6 throttlings becoming low-temp low-pressure, absorb the salt solution heat and gasified, become the gas that contains small amount of liquid (small working medium drop and lubricating oil), enter gas-liquid separator, fall into the bottom after small amount of liquid is separated, overheated refrigerant vapour is sucked the refrigerant vapour that is compressed into high pressure-temperature by compressor.The liquid of separating contains working medium and lubricating oil, lamination takes place in both, oil is on the upper strata, working medium in lower floor after working medium is drawn back compressor, the oil-enriched layer of thickness settles down and is uninterruptedly heated reduction viscosity by the higher liquid of relative temperature in the liquid reservoir, makes lubricating oil constantly enter compressor continuously uniformly.
Claims (1)
1, three-in-one refrigerating plant, the liquid reservoir (1) that it is connected by pipeline, gas-liquid separator and heat exchanger, condenser (3), compressor (4), evaporimeter (5), heating power expansion valve (6) is formed, it is characterized in that: gas-liquid separator and heat exchanger integrate and are the gas-liquid separator heat exchanger (2) of holding concurrently, and are provided with liquid reservoir (1) in the hold concurrently periphery of heat exchanger (2) of gas-liquid separator.
