Abstract
The utility model relates to an ammonia water-cooling device, which is characterized in that a compressor is respectively connected with a condenser and an evaporator through an air exhaust pipe and an air suction pipe; a feeding pipe between the condenser and the evaporator is provided with an expansion valve and ammonia liquor is restricted through the expansion valve. The refrigerating oil of the compressor is made of PAG synthetic oil which can be mutually soluble with ammonia so that the synthetic oil can automatically return to the compressor with the circulation of the ammonia. In order to avoid leakage, the compressor adopts a shielded compressor while the condenser and the evaporator adopt a full-welded plate type structure and the evaporator is a dry evaporator. The utility model has the advantages of simple structure and high safety.
Description
The utility model relates to a kind of refrigerating plant, particularly a kind of ammonia cold water device.
Usually; be widely used in the hotel; hospital; the cinema; place air conditionings such as machine room; cooling in the industrial manufacture process and the handpiece Water Chilling Units that needs cryogenic freezing water place; generally adopt CFC; HCFC makes cold-producing medium; this class CFC; CFC in the HCFC handpiece Water Chilling Units; HCFC all belongs to the freon material; it not only can damage the ozone layer; and; also can cause the greenhouse effects of the earth; unfavorable to environmental protection, ammonia is as a kind of natural refrigerant, and it neither can damage the ozone layer; also can not cause the greenhouse effects of the earth; cheap in addition, thermal performance is superior, so ammonia cold water device has begun CFC alternative; the HCFC handpiece Water Chilling Units.Existing ammonia cold water device mainly by compressor, condenser, evaporimeter and be arranged on compressor and condenser between oil eliminator, be arranged on liquid separator between condenser and evaporimeter, be arranged on scavenge oil pump between compressor and the evaporimeter etc. and form.Because what be provided with in the unit is liquid separator, flooded evaporator, and adopts the ball-cock assembly throttling, gravity force liquid-supply, so it is it is big to make that unit fills the ammonia amount, unfavorable to safety.And the mineral oil that refrigeration oil adopts in this unit for not dissolving each other with ammonia, be gathered in the heat exchanger wall for fear of oil film, hinder and conduct heat, be provided with oil eliminator, in order to guarantee automatic oil return, be provided with oil catcher, scavenge oil pump, oil return valve and pipeline thereof, this not only makes many, the complex structure of unit moving component, and makes its reliability relatively poor.Again because compressor adopts be opened compressor, very easily produce leakage phenomenon so seal, and condenser and evaporimeter all are to adopt the stainless steel plate type structure that clamps by sealing ring sealing, bolt, also easily make long seal perimeter generation leakage by the axle envelope.
The purpose of this utility model is to provide a kind of direct expansion feed flow formula ammonia cold water device, and it is simple in structure, safe and reliable, efficient is higher.
Its concrete solution is: compressor is connected with condenser and evaporimeter respectively by blast pipe and air intake duct, and the feed pipe that is connected between condenser and evaporimeter is provided with expansion valve, ammoniacal liquor can carry out throttling by it, the PAG artificial oil that the employing of compressor and freeze oil can be dissolved each other with ammonia makes its this artificial oil return compressor automatically with the circulation of ammonia.In addition then, for avoiding leakage phenomenon, compressor adopts the protected type compressor, and condenser and evaporimeter adopt full welding aluminium-made plate type structure.Expansion valve is heating power expansion valve or electric expansion valve.Evaporimeter is a dry evaporator.
The utility model adopts dry evaporator, protected type compressor, and by expansion valve throttling, direct expansion feed flow, and compressor adopts the PAG artificial oil that can dissolve each other with ammonia as refrigeration oil, make it fill not only that the ammonia amount significantly reduces, security is improved, good sealing effect, and, parts such as the oil eliminator that is provided with in the prior art, liquid separator, oil catcher, scavenge oil pump have been exempted, the simplification of structure has not only improved reliability greatly, and has guaranteed the high efficiency of condenser and evaporimeter.
In conjunction with the accompanying drawings the utility model is described in detail below by embodiment.
Fig. 1 is the utility model schematic flow sheet.
Fig. 2 is the utility model structural representation front view.
Fig. 3 is the utility model structural representation vertical view.
Among Fig. 1, Fig. 2, Fig. 3, compressor (5) is the protected type compressor, and it is fixed on frame (29) top by bolt (26), is provided with rubber damper (25) between compressor (5) and the frame (29).Condenser (21), evaporimeter (11) are fixed on frame (29) middle part by bolt (27), (28) respectively, and wherein evaporimeter (11) is a dry evaporator.Compressor (5) is connected with condenser (21) and evaporimeter (11) by blast pipe (3), air intake duct (7) respectively, be connected with stop valve (19), filter (16), magnetic valve (8), expansion valve (9) between condenser (21) and evaporimeter (11), and, be connected with respectively on blast pipe (3), the air intake duct (7) stop valve (4) and (6) and on be connected with the bursting tube (23) of safety valve (1), stop valve (2), safety valve (12), stop valve (13) and (14) respectively.The ammonification pipe (18) that is connected with stop valve (17) on it is connected on the feed pipe (15), is used for and blast pipe (3), feed pipe (15), air intake duct (7) flange connecting (22), (20), (10), (24) and be respectively equipped with on the condenser (21), evaporimeter (11).Condenser (21), evaporimeter (11) all adopt does not have leakage, the higher full welding aluminium-made plate type structure of thermal conductivity factor.Make cold-producing medium with ammonia in the device, and the PAG artificial oil that the employing of compressor and freeze oil can be dissolved each other with ammonia.
During work, the high pressure-temperature ammonia after the compression enters condenser (21), contacts with the condenser plate and is condensed into normal temperature high voltage liquid, and condenser heat is taken away by the cooling water of an other side.The high normal pressure and temperature ammoniacal liquor that is flowed out by condenser (21) bottom enters expansion valve (9) after filtering, the throttling step-down is the low-pressure low-temperature gas-liquid mixture, enter evaporation gasification in the evaporimeter (11), during the ammoniacal liquor gasification, need to absorb a large amount of heats, evaporimeter (11) is so the temperature of the interior refrigerating medium water that passes through is minimized, and the ammonia steam after the evaporation heat absorption reenters compressor (5) recompression.Circulation just can constantly be carried chilled water to the external world so continuously.
