The embodiment of the invention discloses a kind of hot air deicing refrigeration system of single-plate plate ice machine; Existing deice that refrigeration compressor air suction pressure is low in the process, pressure at expulsion is low to solve, can not deice and even the low excessively problem that causes stopping compressor operating of refrigeration compressor low pressure.
A kind of hot air deicing refrigeration system of single-plate plate ice machine; Shown in accompanying drawing 1; The output of refrigeration compressor 1 is connected with high-efficiency oil separator 2; High-efficiency oil separator 2 separates out with the oil in the cold-producing medium; And pass through pipeline and carry back in the refrigeration compressor 1, the refrigerant gas output of high-efficiency oil separator 2 is connected with water-cooled condenser 5, and pressure reduction magnetic valve 3 is arranged on the refrigerant gas output of high-efficiency oil separator 2; Exhaust by-pass valve 4 is connected in parallel on the two ends of pressure reduction magnetic valve 3; Water-cooled condenser 5 is connected with band heat exchange gas-liquid separator 7, also is provided with feed flow filter 6 in the outlet of water-cooled condenser 5, and the cold-producing medium that is used for liquid towardsization filters; Liquid supply electromagnetic valve 8, heating power expansion valve 9 are connected in series between the input of liquid refrigerant output and plate slab sheet heat exchanger 11 of band heat exchange gas-liquid separator 7; The output of plate slab sheet heat exchanger 11 is connected in series with return-air magnetic valve 13 and return-air filter 15 successively, and being parallel with diameter at the two ends of return-air magnetic valve 13 is the short circulation pipe 12 of 6mm, and return-air filter 15 is connected with band heat exchange gas-liquid separator 7; The gas output end of band heat exchange gas-liquid separator 7 is connected with refrigeration compressor 1; Between the outlet side of the output of pressure reduction magnetic valve 3 and return-air filter 15, be serially connected with bypass solenoid valve 17 and KVC pressure-control valve 18, between the refrigerant gas output of high-efficiency oil separator 2 and knockout 10, be connected with feed flow hot gas solenoid valve 16, between the output of the refrigerant gas output of high-efficiency oil separator 2 and plate slab sheet heat exchanger 11, also be connected with return-air hot gas solenoid valve 14.
The course of work of above-mentioned hot air deicing refrigeration system of single-plate plate ice machine is divided into two processes; Ice-making process with deice process; Wherein: ice-making process is refrigeration compressor, pressure reduction magnetic valve, liquid supply electromagnetic valve, the unlatching of return-air magnetic valve, and bypass solenoid valve, liquid supply electromagnetic valve, return-air hot gas solenoid valve are closed.Refrigeration compressor compresses cold-producing medium; Cold-producing medium becomes the gas of HTHP; The employed oil of the compressor of process of refrigerastion is separated and carry back refrigeration compressor through high-efficiency oil separator; Refrigerant gas through high-efficiency oil separator enters into water-cooled condenser through pressure reduction magnetic valve and exhaust release valve ball, and the liquid refrigerant of warm high pressure in becoming, the liquid refrigerant of middle temperature high pressure become the liquid refrigerant of low-temp low-pressure through band heat exchange gas-liquid separator, liquid supply electromagnetic valve, heating power expansion valve, knockout and capillary; Carry out heat exchange through plate slab sheet heat exchanger at last; Outside the pipe of plate slab sheet heat exchanger, carry out aproll,, become the refrigerant gas of low-temp low-pressure because the liquid refrigerant of the low-temp low-pressure in the plate slab sheet gasifies; In this process, absorb heat owing to gasifying; So that the water that is dispersed on the plate slab sheet heat exchanger is lowered the temperature rapidly, become ice, be that the gas refrigerant of low-temp low-pressure compresses through entering refrigeration compressor behind return-air magnetic valve and the return-air filter through the cold-producing medium behind the plate slab sheet heat exchanger.
Deice in the process; Become the gas of HTHP through the cold-producing medium of refrigeration compressor; High temperature and high pressure gas through high-efficiency oil separator gets into plate slab sheet heat exchanger through feed flow hot gas solenoid valve, knockout and capillary; Because the temperature of cold-producing medium is very high, the ice evaporation that is attached on the plate slab sheet heat exchanger is melted, the heat that the thawing of in this process, icing absorbs around the heat exchanger is lowered the temperature environment temperature.The ice making process of deicing that hot air deicing refrigeration system of single-plate plate ice machine is logical to be gone over time reaches the purpose of refrigeration.
Be in series with KVC pressure-control valve and bypass solenoid valve at the output of pressure reduction magnetic valve and the outlet side of return-air filter in the hot air deicing refrigeration system of single-plate plate ice machine that provides in the embodiment of the invention; When the refrigerant gas of HTHP deices; The KVC pressure-control valve can be regulated its aperture according to the pressure behind the valve, guarantees with the pressure in the heat exchange gas-liquid separator identically with pressure in the normal ice-making process, has solved that to deice pressure of inspiration(Pi) in the process of refrigerastion low; Pressure at expulsion is low; Can not deice and refrigeration compressor low pressure is low excessively, can stop the problem of the operation of compressor automatically, and be provided with the pressure reduction magnetic valve in the outlet of high-efficiency oil separator; The shut off differential pressure magnetic valve can improve high temperature and high pressure gas pressure; Increased the speed that system deices, high-temperature gas can flow through exhaust by-pass valve, to guarantee systemic circulation.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the present invention.Multiple modification to these embodiment will be conspicuous concerning those skilled in the art, and defined General Principle can realize under the situation that does not break away from the spirit or scope of the present invention in other embodiments among this paper.Therefore, the present invention will can not be restricted to these embodiment shown in this paper, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
