Abstract
The utility model discloses a large power modularized wind source thermal pump machine set comprising a base on which a compressor and a chiller are installed, a surface cooler and a thermal expansion valve are arranged on the compressor and the chiller, a liquid distributing pipe connected with the surface cooler takes a shape of smooth arc, the surface cooler uses a large capacity tube heat exchanger comprising two spiral tubes, an upper one and a lower one, in which inner spiral tubes are provided. The utility model is capable of effectively improving the heating(cooling) capacity and the heating(cooling) effect of the wind source thermal pump machine set.
Description
Affiliated technical field
The utility model relates to compression heat pump systems technology field.
Background technology
HEAT PUMP TYPE WATER CHILLERS is a kind of idle call heat pump that generally uses at present, and in this wind source heat pump, cold (heat) source comes from atmosphere, and the heat exchange of itself and atmosphere is finished by surface cooler, and cold-producing medium is assigned in each pipeline of surface cooler by liquid-dividing head.Common way is separating tube to be bent certain angle connect liquid-dividing head and surface cooler in horizontal flat vertical mode, but because separating tube bending angle difference produces different resistances to the medium that flows therein, influences the separatory effect.In addition, the resistance that is subjected in the separating tube medium with knuckle is bigger, is unfavorable for media flow, and it is stifled also to be easy to generate ice, influences refrigeration.The heat exchange of wind source heat pump unit and cold (heat) matchmaker water is finished by freezing water apparatus, in high-power wind source heat pump unit, freezing water apparatus adopts shell and tube exchanger usually, its heat transfer coefficient is little, heat exchange efficiency is low, and complex structure has increased equipment investment, the easy short circuit of cooling liquid has reduced heat-transfer effect.
Summary of the invention
The purpose of this utility model is exactly at the deficiencies in the prior art, provides a kind of refrigeration (heat) to measure high-power modular wind source heat pump unit big, good effect of heat exchange.
For achieving the above object, the technical solution adopted in the utility model is: it comprises base and the compressor and the freezing water apparatus that are installed on the base, surface cooler and heating power expansion valve are installed above compressor and freezing water apparatus, be connected with some separating tubes by liquid-dividing head between surface cooler and the heating power expansion valve, it is level and smooth circular-arc that separating tube is, the one end links to each other with the input of surface cooler, and the other end is connected on the liquid-dividing head by being oriented in a tangential direction with the liquid-dividing head axis.Freezing water apparatus adopts big capacity double-tube heat exchanger, and said big capacity double-tube heat exchanger comprises that the separate inside of refrigerant system is equipped with the last screw shell and the following screw shell of pipe in the spiral.
Adopt technique scheme, suffered resistance equilibrium during media flow in the separating tube, separatory is effective, has reduced the heat exchange area of surface cooler, and the suffered resistance of medium is little, can effectively prevent the generation that stagnant ice is stifled, improves (heat) effect of freezing.Big capacity double-tube heat exchanger is guaranteeing to have strengthened heat exchange area under the certain situation of cold-producing medium overall resistance, thereby has improved refrigeration (heat) amount of unit.Shape is mobile in the shape of a spiral in shell for refrigerating medium, has certain perturbation action, makes laminar heat transfer become turbulent heat transfer.The screw shell that pipe in the spiral is equipped with in inside has improved resistance to deformation and the freeze proof ability of splitting.

Fig. 1 is a front view of the present utility model, shows its overall structure;
Fig. 2 is the connection diagram of separating tube and liquid-dividing head and surface cooler;
Fig. 3 is the front view of big capacity double-tube heat exchanger.
The specific embodiment
In the embodiment shown in the figures, the casing 7 that the utlity model has base 3 and be fixed as one with base 3, compressor 1, freezing water apparatus 2 and electrical control cubicles 6 are installed on base 3, above compressor 1 and freezing water apparatus 2, surface cooler 4 and heating power expansion valve are installed, are connected with some separating tubes 9 by liquid-dividing head 8 between surface cooler 4 and the heating power expansion valve by skeleton 5.It is level and smooth circular-arc that separating tube 9 is, the equal in length of each separating tube 9, and the one end links to each other with the input of surface cooler 4, and the other end is connected on the liquid-dividing head 8 by being oriented in a tangential direction with liquid-dividing head 8 axis.Compressor 1 adopts semi-hermetic screw compressor, and freezing water apparatus 2 adopts big capacity double-tube heat exchanger.Said big capacity double-tube heat exchanger comprises that the separate inside of refrigerant system is equipped with the last screw shell 12 and the following screw shell 11 of pipe 10 in the spiral, the water inlet pipe of upper and lower screw shell is connected on the same three-way pipe 13, and its outlet pipe is connected on another three-way pipe 14.Pipe 10 is evenly distributed in the shell with 10-45 degree helical angle in the spiral.
