Abstract
The utility model relates to a deep-cooling refrigerator set structure, which is mainly composed of a high-temperature unit, a low-temperature unit, a refrigerant circulating system, etc. The utility model is characterized in that a high-temperature refrigerating unit is formed by the connection of a high-temperature compressor, a water condenser, an expansion valve, and an evaporative condenser by refrigerant pipelines; the low-temperature refrigerating unit is formed by the connection of a low-temperature compressor, an evaporative condenser, a low-temperature expansion valve, and an evaporator by refrigerant pipelines; the refrigerant circulating system is formed by the connection of an evaporator, a low-temperature circulating pump, a coldness using service position by refrigerant medium pipelines; a water precooler is arranged between the low-temperature compressor of the low-temperature refrigerating unit and the evaporative condenser. The utility model has the advantages of simple structure, high cooling efficiency, and high safety.
Description
The utility model relates to a kind of deep cooling set structure.
Formula deep cooling unit repeatedly again, cryogenic compressor uses the R23/R13 cold-producing medium.HTHP fluorine Lyons gas of discharging from compressor will obtain condensation the evaporative condenser of high temperature compressed machine.If fluorine Lyons gas of this HTHP directly enters evaporative condenser, will increase the thermic load of high temperature refrigeration unit greatly.The refrigeration work consumption that this certainly will will improve the high temperature unit causes the raising of power consumption and manufacturing cost.On the contrary, if do not improve refrigeration work consumption, the refrigeration of cryogenic refrigeration unit will directly be influenced, even the cryogenic refrigeration unit has the possibility of frequent jumping car.In addition, the temperature in fluorine Lyons is too high, also has refrigerator oil and decomposes the danger that manifold pressure is too high.
It is a kind of simple in structure that the purpose of this utility model is to provide, refrigerating efficiency height, safe and reliable deep cooling set structure.
For achieving the above object, the utility model is taked following design: this deep cooling set structure, mainly by the high temperature unit, cryogenic unit, formations such as coolant circulating system, described high temperature refrigeration unit by refrigerant tubing with high temperature compressed machine, water condenser, expansion valve, evaporative condenser connects to form, described cryogenic refrigeration unit by refrigerant tubing with cryogenic compressor, evaporative condenser, the low-temperature expansion valve, evaporimeter connects to form, described coolant circulating system by the refrigerant medium pipeline with evaporimeter, the low temperature circulating pump, connect to form cryogenic compressor in the cryogenic refrigeration unit with cold station, settle water precooler between the evaporative condenser.
Because the utility model adopts above technical scheme, the utility model is simple in structure, and the refrigerating efficiency height is safe and reliable.During the cryogenic refrigeration cell operation, HTHP fluorine Lyons gas of discharging from cryogenic compressor at first enters water precooler, and recirculated cooling water and fluorine Lyons gas carry out effective exchange heat, and fluorine Lyons gas of about 150 ℃ is reduced to degree near water temperature.This will reduce the pressure of pipeline, reduce the temperature of oil, reduce the thermic load of evaporative condenser, improve the refrigerating efficiency of whole unit.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model one embodiment schematic diagram
As shown in Figure 1, this deep cooling set structure of the utility model, mainly by the high temperature unit, cryogenic unit, formations such as coolant circulating system, described high temperature refrigeration unit by refrigerant tubing 11 with high temperature compressed machine 1, water condenser 2, expansion valve 3, evaporative condenser 4 connects to form, described cryogenic refrigeration unit by refrigerant tubing 12 with cryogenic compressor 6, evaporative condenser 4, low-temperature expansion valve 7, evaporimeter 8 connects to form, described coolant circulating system by refrigerant medium pipeline 13 with evaporimeter 8, low temperature circulating pump 9, connect to form cryogenic compressor 6 in the cryogenic refrigeration unit with cold station 10, settle water precooler 5 between the evaporative condenser 5.
High temperature compressed machine 1, water condenser 2, expansion valve 3, evaporative condenser 4, formed the high temperature refrigeration unit, the heat that produces in the work is taken away by water condenser 2.
Cryogenic compressor 6, evaporative condenser 4, water precooler 5, low-temperature expansion valve 7, evaporimeter 8, formed the cryogenic refrigeration unit.The heat that produces in the work is taken away by evaporative condenser.
The effect of water precooler 5 is HTHP fluorine Lyons gas coolings that compressor is discharged, and alleviating the thermic load of high temperature unit, and makes compressor oil be unlikely decomposition.
Below only be an embodiment of the present utility model, any based on equivalents of the present utility model all within protection domain of the present utility model.
