Abstract
The utility model discloses a heat pump system provided with an economizer. The heat pump system comprises a condenser (3), a first dry filter (11), an evaporator (14) and a compressor (2) sequentially connected in series to form a circulating loop. An economizer (7) is connected between the condenser and the first dry filter. The output end of the condenser is divided into two branches for outputting, one branch directly passes through the economizer and then is communicated to the first dry filter, and the other branch is communicated to the economizer through a second dry filter and communicated to an air supply port at the middle part of the compressor through the economizer. The thermodynamic performance of the conventional heat pump cycle can be improved by the heat pump cycle with the economizer. The heating quantity of a heat pump unit is improved, the refrigerating quantity of the unit is greatly increased, and the refrigerating coefficient is obviously improved. The problems of insufficient heating capacity of the heat pump system under a low-temperature working condition and over high exhaust temperature of the compressor are solved, and the application range of the heat pump system is expanded.
Description
Technical field
The present invention relates to a kind of heat pump, more particularly, relate to the improvement of compressor section in the heat pump.
Background technology
There is the not enough and too high problem of compressor exhaust temperature of heating capacity in heat pump under the prior art, and this just need design one overlap the method that can improve the heat pump operating efficiency under the certain condition of power consumption
Summary of the invention
The present invention aims to provide a kind of heat pump with economizer, and the unit refrigerating capacity is significantly increased, and coefficient of refrigerating performance obviously improves.Solved the not enough and too high problem of compressor exhaust temperature of heat pump heating capacity under worst cold case, made the range of application of heat pump obtain expansion.
In order to achieve the above object, the invention provides a kind of heat pump that is provided with economizer, comprise condenser, first device for drying and filtering, evaporimeter, compressor that closed circuit is contacted successively.Between described condenser and described first device for drying and filtering, be connected with an economizer.The output bifurcation of described condenser is exported along separate routes, and a shunt directly passes to described first device for drying and filtering through behind the described economizer; Another shunt passes to described economizer and is communicated to the gas supplementing opening that described compressor middle part is provided with through described economizer through second device for drying and filtering.Wherein, be positioned at the described first device for drying and filtering both sides and be provided with first ball valve and second ball valve, and the pipeline before the described evaporimeter is provided with first expansion valve; On the pipeline between the gas supplementing opening of described economizer and described compressor, be disposed with magnetic valve and stop valve; And the both sides of second device for drying and filtering are positioned at and are respectively arranged with the 3rd ball valve and second expansion valve on the branch road.
The heat pump cycle of band economizer of the present invention can make the thermodynamic property of former conventional heat pump cycle be improved.The heating capacity of source pump is improved.Though this is to reduce delivery temperature because set up economizer tonifying Qi meeting in the compressor, can not reduce condensation heat, can make it on the contrary increases.This is the medium pressure gas air inlet after air entry complete closed of compressor low pressure that covers because of the secondary suction chamber, and therefore former inspiratory capacity is constant, and the gross exhaust gas of compressor has increased, so the heating capacity of compressor must increase.This system improves about 14.6% at the more common unit of heating capacity under the heat pump operating mode, and COP improves about 4.7%; The more common unit of refrigerating capacity improves 6.4% under cooling condition, and COP improves 2.8%.Delivery temperature is reduced more than 12 ℃, reduce the hydrojet loss.
Description of drawings
Fig. 1 is the theory structure schematic diagram that is provided with the heat pump of economizer.
The specific embodiment
A kind of heat pump that is provided with economizer shown in Figure 1 comprises condenser 3, first device for drying and filtering 11, evaporimeter 14, compressor 2 that closed circuit is contacted successively.Between the condenser 3 and first device for drying and filtering 11, be connected with an economizer 7.The output bifurcation of condenser 3 is exported along separate routes, and a shunt directly passes to first device for drying and filtering 11 through behind the economizer 7, and another shunt passes to economizer 7 and is communicated to the gas supplementing opening that compressor 2 middle parts are provided with through economizer 7 through second device for drying and filtering 5.Wherein, be positioned at first device for drying and filtering, 11 both sides and be provided with first ball valve 10 and second ball valve 12, and the pipeline before the evaporimeter 14 is provided with first expansion valve 13; On the pipeline between the gas supplementing opening of economizer 7 and compressor 2, be disposed with magnetic valve 8 and stop valve 9; And the both sides of second device for drying and filtering 5 are positioned at and are respectively arranged with the 3rd ball valve 4 and second expansion valve 6 on the branch road.
Fig. 1 is the fundamental diagram of the heat pump of band economizer.System is divided into major loop and tonifying Qi loop two parts.A middle gas supplementing opening is set at the middle part of compressor.The high temperature refrigerant gas that compressor is discharged enters condenser, carries out heat exchange with well water or system water in condenser, and being condensed is called liquid.It is major loop that a refrigerant liquid part that goes out condenser directly enters economizer, and throttling is depressurized to intermediate pressure to enter economizer be the tonifying Qi loop another part through expansion valve.Wherein, the course of work and the principle of economizer are as follows: the cold-producing medium that throttling is depressurized to intermediate pressure in the economizer made it cold with refrigerant liquid heat exchange without throttling, and the refrigerant liquid of crossing after cold enters evaporimeter through expansion valve.And that part of cold-producing medium that becomes superheated steam after the heat exchange enters compressor through gas supplementing opening under middle pressure condition.
The above; only be the preferable specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or change according to technical scheme of the present invention and inventive concept thereof, all should be encompassed within protection scope of the present invention.
