Description

There is the degree of depth of better distribution effects to cross the heat pump that cold collector tube liquid phase is distributed
Technical field
The utility model relates to heat pump.
Background technology
If entering into the cold-producing medium of evaporimeter is two-phase, then may exist cold-producing medium in the different circuit of coil pipe, to distribute uneven problem.Therefore, how to improve that the distribution effects of cold-producing medium in evaporimeter is a problem that needs to be resolved hurrily in the industry in the heat pump.
The utility model content
The purpose of this utility model is to provide a kind of has the degree of depth of better distribution effects to cross the heat pump that cold collector tube liquid phase is distributed.
For the degree of depth that better distribution effects is arranged that realizes described purpose is crossed the heat pump that cold collector tube liquid phase is distributed, comprise compressor, condenser, evaporimeter, be characterized in, between evaporimeter and condenser, be provided with degree of depth subcooler, condenser to the major loop of degree of depth subcooler has Zhi Huilu, this Zhi Huilu is through being connected the low pressure air suction side of compressor behind this degree of depth subcooler, a cold-producing medium part of coming out from condenser flows into described Zhi Huilu, the cold-producing medium of described Zhi Huilu flow through behind the Zhi Huilu expansion valve among this Zhi Huilu with major loop in the flow through cold-producing medium of degree of depth subcooler carry out heat exchange, the gaseous refrigerant of described Zhi Huilu flow into the low pressure air suction side of compressor then, the cold-producing medium of the degree of depth of flowing through in major loop subcooler is cooled to the liquid phase that has than big supercooling degree, is assigned to each loop of evaporimeter to such an extent as to be liquid phase behind the major loop expansion valve in the cold-producing medium process major loop.
Because single-phase refrigerant is distributed in each loop of evaporator coil, so distribution effects is good.
In the preferred embodiment of described heat pump, described cold-producing medium is assigned to each loop of evaporimeter by liquor collecting system, and described liquor collecting system comprises heating mode collector tube, refrigeration mode collector tube, many capillaries and Duo Gen coil circuit pipe; The heating mode collector tube inserts the refrigeration mode collector tube, has the heating mode entrance, and the end of refrigeration mode collector tube has the refrigeration mode outlet; Capillary inserts the coil circuit pipe, entrance capillaceous is inserted in the heating mode collector tube, the outlet of coil circuit pipe is inserted in the refrigeration mode collector tube, under refrigeration mode, the cold-producing medium that comes out from the heat exchange coil of evaporimeter is through each coil circuit pipe, and then enter into the refrigeration mode collector tube, flow to major loop from the refrigeration mode outlet then; Under heating mode, liquid phase refrigerant flows out from the major loop expansion valve, enters into heating mode collector tube entrance, and then is assigned to capillary, and cold-producing medium is assigned to every loop pipe then, enters into the heat exchange coil of evaporimeter at last.
Aforementioned collector tube have take up room little, the characteristics of compact conformation.
Description of drawings
Fig. 1 is the system block diagram of heat pump among the utility model embodiment, and what system block diagram showed is the signal simplified block diagram of flow of refrigerant under heating mode.
Fig. 2 is the front view of liquor collecting system among the utility model embodiment.
Fig. 3 is the left view of liquor collecting system among the utility model embodiment.

The specific embodiment
Simplification heats shown in the schematic diagram as Fig. 1, and heat pump comprises compressor 12, condenser 13, degree of depth subcooler 14 and evaporimeter 11, and cold-producing medium flows between compressor 12, condenser 13, degree of depth subcooler 14 and evaporimeter 11, and circulation heats.
Major loop between condenser 13 and the degree of depth subcooler 14 has Zhi Huilu 23, this Zhi Huilu 23 guides cold-producing medium to the Zhi Huilu expansion valve, the cold-producing medium of Zhi Huilu 23 is behind the Zhi Huilu expansion valve, again with major loop in carry out heat exchange through the cold-producing medium in the degree of depth subcooler 14, so that the cold-producing medium in the major loop carries out degree of depth cooling, be to have the very liquid phase of big supercooling degree so that enter into the cold-producing medium of major loop expansion valve, its outlet still is liquid phase, in case cold-producing medium is single-phase, the effect that its distribution enters into evaporimeter 11 will improve greatly.On the other hand, after cold-producing medium among the Zhi Huilu 23 and degree of depth subcooler 14 carried out heat exchange, owing to be evaporated, its steam pressure was directed into the low pressure air suction side of compressor 12, reduce even enter the major loop flow of evaporimeter 11 like this, thereby reduced the pressure drop of cold-producing medium in evaporimeter 11.
Therefore, the effect that improves the cold-producing medium distribution effects and reduce the pressure drop of cold-producing medium in evaporimeter 11 has been played in the acting in conjunction of degree of depth subcooler 14 and Zhi Huilu 23 really.
To shown in Figure 4, the liquor collecting system of crossing cold collector tube liquid phase distribution for the degree of depth has heating mode collector tube 101, refrigeration mode collector tube 102, capillary 113 and coil circuit pipe 114, collector end cap 105, refrigeration mode outlet 106 and heating mode entrance 107 as Fig. 2.Heating mode collector tube 101 inserts refrigeration mode collector tube 102, and capillary 113 inserts coil circuit pipe 114, and the entrance of capillary 113 is inserted in the heating mode collector tube 101, and the outlet of coil circuit pipe 114 is inserted in the refrigeration mode collector tube 102.End at refrigeration mode collector tube 102 is provided with refrigeration mode outlet 106.
Under refrigeration mode, the cold-producing medium that comes out from heat exchange coil passes through each coil circuit pipe 114, and then enters into refrigeration mode collector tube 102, flows to liquid pipeline from refrigeration mode outlet 106 then.
Under heating mode, liquid refrigerant flows out from the major loop expansion valve, enters into heating mode entrance 107, and then is assigned to capillary 114, and cold-producing medium enters into every loop pipe 113 then.
Collector end cap 105 is used for brazing heating mode collector tube 101 and refrigeration mode collector tube 102, and the two is fixed.
