Abstract

An energy-saving water-supply air-conditioner belongs to the field of air-conditioner technique, mainly aiming at solving the problems of common water-supply air-conditioner that the efficiency of heat-exchanger is low; the processing is difficult and the cost is high. The air-conditioner consists of a compressor 1, a four-branch solenoid valve 2, a capillary 3, a plastic-bushing type condenser 4, a plastic-bushing type evaporator 5, a refrigerant pump 6, a water-supply pump 7, a water-supply 8 and a user-end 9. A plastic-bushing energy-exchanger is used as a heat-exchanger. The air-conditioner has the advantages of light weight, small volume, low cost, easy processing, high heat-exchanging rate and energy conservation. And the air-conditioner can be used not only as a central air-conditioner but also as a single room air-conditioner.

Description

The water source energy-saving type air conditioner

Technical field:

The utility model relates to a kind of air-conditioning technical, relates in particular to a kind of air-conditioning technical that utilizes the water source to carry out thermal energy exchange.

Background technology:

At present, in existing technology, coil pipe immersion, shell-and-tube heat exchanger and metallic sheath tubular type heat exchanger are generally used in the heat exchange of source air-conditioner water, the highest in the above-mentioned heat exchanger with metallic sheath tubular type heat exchanger efficiency, but reason owing to structure and material, make metallic sheath tubular type heat exchanger have problems such as difficulty of processing is big, cost height, seldom use aborning, so the gross efficiency of source air-conditioner water is not very good.

Summary of the invention:

Technical scheme of the present invention is exactly the problem at above-mentioned existence, creates a kind of plastic sheath tubular type heat exchanger, and with condensation and the evaporimeter of this heat exchanger as air-conditioning, reaches purpose of energy saving thereby improve heat exchange efficiency.

Plastic sheath tubular type heat exchanger of the present invention is made up of plastic tube, copper tube and three-way piece.Copper tube is made inner sleeve, plastic tube is made outer tube, is processed into by suit.Plastic tube is a water pipe and engineering pipe.

Double pipe heat exchanger of the present invention, plastic tube is wrapped in the copper tube periphery, source water or the chilled water gap between plastic tube and the copper tube of flowing through, cold-producing medium in the parcel copper tube, and with reverse the flowing of cold-producing medium, source water (or chilled water) carries out the high temperature difference forced convertion from the beginning to the end with cold-producing medium, makes heat exchange efficiency improve greatly.Make the condenser and the evaporimeter of source air-conditioner water with above-mentioned double pipe heat exchanger, the main frame cost of air-conditioning is reduced, weight saving, the life-span prolongs, and the water source capacity usage ratio improves, and reaches the energy-efficient optimum efficiency of complete machine.

Description of drawings:

Accompanying drawing one is the schematic diagram of water source energy-saving type air conditioner.

Accompanying drawing two is plastic sheath tubular type heat exchanger structure figure.

The specific embodiment:

The water source energy-saving type air conditioner, the transducer with common source air-conditioner water repacks special plastic sheath tubular type heat exchanger into exactly, and structure is shown in accompanying drawing one.The water source energy-saving type air conditioner is made up of compressor 1, four way solenoid valve 2, capillary 3, plastic sheath tubular type condenser 4, plastic sheath tubular type evaporimeter 5, refrigerant water pump 6, water source water pump 7, water source 8, user side 9.

In when refrigeration, the water of 8 the insides, water source is pressed into condenser 4 through water pump 7, in transducer with the forced convertion of cold-producing medium high speed, because the temperature difference is big, flow velocity is fast, makes the vapours of condenser 4 the insides liquefy rapidly, and in the exit near the temperature at water source, finish the heat exchange between cold-producing medium and source water.Through condenser 4 overcooled cold-producing mediums, by the red copper in-tube evaporation heat absorption of capillary 3 in evaporimeter 5 the insides, because of the chilled water in the evaporimeter 5 is forced from being pressed in the other direction by water pump 6, so that the heat exchanger effectiveness between cold-producing medium and the chilled water is very high, the very fast cooled dose of absorption of the heat of user side 9, and by compressor 1, cross valve 2 constitutes a thermal cycle process with heat transferred condenser 4.When heating, four way solenoid valve 2 exchanges condenser and evaporator function, and operation principle is identical with refrigeration.

Shown in accompanying drawing two, plastic sheath tubular type transducer is by copper tube 16, plastic tube 14, water outlet three-way piece 12, water inlet three-way piece 19, epoxy resin water inlet end socket 13, epoxy resin water outlet end socket 20, the excessive connector 15 of plastics water inlet pipe, the excessive connector 21 of plastics outlet pipe, water inlet 11, water out 18, refrigerant inlet 10, refrigerant outlet 17 is formed.

During processing plastic bushing type transducer, earlier with copper tube 16, insert than in its plastic tube 14 of short 60 centimeters, copper pipe stretches out equal length at the plastic tube two ends.Three-way piece and excessive tube connector captacula are connect (or bonding), are enclosed within the copper pipe two ends, and excessive tube head and plastic tube is bonding, treat adhesive curing after, according to material of using and installation needs transducer is bent to specific shape.After external form was fixing, both available epoxy or other material be the outer side seal of three-way piece, also plays simultaneously copper tube is fixed on effect on the three-way piece.Because the water pressure that flows in the cavity of plastic bushing and copper tube is not high, therefore sealing is easy to realize.In use, water is gone into from import 18, goes out from exporting 11, and cold-producing medium is reverse flow with it, goes into from import 10, and outlet 17 goes out, because the convection current between cold-producing medium and the water is very strong, long flow path does not have hot short-circuit loss between each gateway, so heat transfer rate is very high.
