Abstract
The utility model discloses a bushing type intermediate heat exchanger for air-conditioning system, comprising a large copper pipe, an interface connecting with condenser liquid refrigerant outlet and gaseous refrigerant outlet are arranged on one end of the large copper pipe, liquid refrigerant outlet and interface connecting with gaseous refrigerant outlet of evaporator are arranged on the other end, a small copper pipe bundle is put in large copper pipe, one end of this small copper pipe bundle is connected with the interface on one end of large copper pipe, the other end is connected with the outlet on the other end of large copper pipe, liquid refrigerant flows from the interface on one end of large copper pipe into small copper pipe bundle, flows out from the outlet on the other end of large copper pipe through small copper pipe bundle. This bushing type heat exchanger could effectively increase heating capacity per unit mass, could reduce harmful superheat in suction pipe, at the same time, avoid icing of the compressor.
Description
Technical field
The utility model relates to a kind of hot pump in low temp hot water unit, specifically, relates to a kind of liquid refrigerant of heat-pump hot-water unit and device that gaseous refrigerant carries out heat exchange of being used for.
Background technology
Among present heat-pump hot-water unit field, in the especially general civilian heat pump water-heating machine system, the circulatory system that heat pump adopts does not consider that the liquid of working medium crosses the influence of cold-peace steam superheating, and these factors all can have influence on the performance of circulation.Under the certain situation of condensing pressure, if can further reduce the temperature of liquid before the throttling, make it be lower than condensation temperature and be in the state of subcooled liquid, then can reduce the flash steam amount that produces after the throttling, and then improve the heating capacity of unit mass.In the heat pump cycle, compressor can not suck the steam of saturation state, vapor (steam) temperature is raise, therefore, suck steam and before compression, be in superheat state.Compress work per mass has increased in the steam superheating circulation, the unit thermic load of condenser has also increased, the steam specific volume that enters compressor has also increased, thereby the quality internal circulating load of working medium has reduced in the compressor unit interval, so the heating capacity of heat pump assembly reduces, unit mass heating capacity, heat pump coefficient all will reduce.And even come the Low Temperature Steam of flash-pot to be in superheat state, its temperature is still very low, particularly in the winter time the time, is easy to cause compressor to freeze.
The utility model content
The purpose of this utility model is to overcome above-mentioned defective of the prior art, a kind of liquid refrigerant of heat-pump-type low-temperature water heating unit and device that gaseous refrigerant carries out heat exchange of being used for is provided, this device can effectively improve the unit mass heating capacity, and can reduce harmful overheated in the aspirating air pipe, avoid compressor to freeze simultaneously.
For achieving the above object, the technical scheme that the utility model provides is as follows: construct a kind of bushing type intermediate heat exchanger that is used for air-conditioning system, comprise large copper pipe, be provided with the outlet that the interface that links to each other with the liquid refrigerant outlet of condenser and air feed attitude cold-producing medium flow out at an end of described large copper pipe, the other end is provided with feed flow attitude cold-producing medium outlet of flowing out and the interface that links to each other with the gaseous refrigerant outlet of evaporimeter, in large copper pipe, be coated with a small copper pipe bundle, one end of this small copper pipe bundle is connected with the interface of large copper pipe one end, the other end is connected with the outlet of the large copper pipe other end, liquid refrigerant flows into small copper pipe bundle from the interface of large copper pipe one end, and flows out from the outlet of the large copper pipe other end through small copper pipe bundle.
Every little copper pipe of described small copper pipe bundle is circumference uniform distribution in large copper pipe.
The inner surface of every little copper pipe of described small copper pipe bundle is shaped on screw thread.
The producing effect of bushing type intermediate heat exchanger that is used for air-conditioning system described in the utility model is: establish the small copper pipe bundle that is circumference uniform distribution by wearing in large copper pipe, the liquid refrigerant that makes the higher temperature that flows out from condensator outlet flows into the small copper pipe bundle that is arranged in the large copper pipe from the interface of large copper pipe one end, and liquid refrigerant flows out from the outlet of the large copper pipe other end again; The gaseous refrigerant of the lower temperature that flows out from evaporator outlet flows in the large copper pipe from the interface of large copper pipe other end bottom, and liquid refrigerant flows out from the outlet on large copper pipe one end top again, and liquid refrigerant and gaseous refrigerant are finished heat exchange in large copper pipe.Can effectively improve the unit mass heating capacity, and can reduce harmful overheated in the aspirating air pipe, avoid compressor to freeze simultaneously.
