Abstract

The utility model is a heat pump air conditioner, comprising a circulation loop formed by a compressor, a low-pressure liquid storage jar, a four-way valve, an outdoor condenser, an indoor evaporator and a high-pressure liquid storage jar (1), wherein a heating restrictive part (A) is provided on the connecting pipeline between the high-pressure liquid storage jar (1) and the outdoor condenser, and a refrigeration restrictive part (B) is provided on the connecting pipeline between the high-pressure liquid storage jar (1) and the indoor evaporator. Via arranging a heating restrictive part on the connecting pipeline between the high-pressure liquid storage jar and the outdoor condenser, and a refrigeration restrictive part on the connecting pipeline between the high-pressure liquid storage jar and the indoor evaporator, the utility model is characterized in that the high-pressure liquid storage jar stores high-pressure refrigerating fluid all along, regardless of whether the system is in refrigeration or heating situation, thereby assuring the system refrigerating fluid of fluent circulation, heating effectively, and prolonging the service life of the compressor.

Description

A kind of heat pump type air conditioner
Technical field
The utility model technology relates to a kind of heat pump type air conditioner, belongs to the improvement technology of heat pump type air conditioner.
Background technology
The heat pump type air conditioner of prior art, high-pressure side are provided with the high pressure fluid reservoir, and low-pressure side is provided with low-pressure liquid storing tank, respectively in order to stocking system at refrigeration, the cold-producing medium of " residue " under the different load when heating.As shown in Figure 1, during refrigeration, the normal temperature high voltage cold-producing medium of the outdoor condenser condenses of process is introduced into the high pressure fluid reservoir, and then by check valve (D), through refrigeration throttle capillary tube (M) throttling step-down, enters indoor evaporator and carry out heat exchange, reaches the refrigeration purpose; When heating, the normal temperature high voltage cold-producing medium that comes out from indoor evaporator enters " high pressure fluid reservoir " after through throttle capillary tube (M) and throttle capillary tube (N) throttling step-down, the cold-producing medium that " pressure pan " of this moment stores is the low-temp low-pressure state, be actually and do low pressure jar usefulness, the cold-producing medium of " residue " when not had pressure pan to be used for storing different load in the system, being easy to occur the part high-pressure refrigerant like this is stored in the outdoor condenser, and compressor lubricant oil also is trapped in the outdoor condenser, can't in time get back to compressor with return-air, cause compressor under mal-condition, to work, therefore influence the service life of compressor, even cause the compressor oil starvation and burn.
The utility model content
The purpose of this utility model is the shortcoming that overcomes prior art, provides a kind of and is freezing or heating under the state, and the high pressure fluid reservoir stores high-pressure refrigerant all the time, and the system refrigerant circulation is smooth, and heating effect is good, improves the compressor heat pump type air conditioner in service life.
The technical scheme that realizes the utility model purpose is: the utility model comprises the closed circuit of being made up of compressor, low-pressure liquid storing tank, cross valve, outdoor condenser, indoor evaporator and high pressure fluid reservoir, the connecting line of its mesohigh fluid reservoir and outdoor condenser is provided with and heats throttle part, and the connecting line of high pressure fluid reservoir and indoor evaporator is provided with the refrigeration throttle part.
The above-mentioned throttle part that heats is formed in parallel by throttle capillary tube and check valve.
Above-mentioned refrigeration throttle part is formed in parallel by throttle capillary tube and check valve.
The utility model heats throttle part owing to having adopted to be provided with on the connecting line of high pressure fluid reservoir and outdoor condenser, on the connecting line of high pressure fluid reservoir and indoor evaporator, be provided with the structure of refrigeration throttle part, no matter system is in refrigeration still heats state, the high pressure fluid reservoir stores high-pressure refrigerant all the time, thereby guaranteed that the system refrigerant circulation is smooth, heating effect is good, improves compressor service life.
Description of drawings
Fig. 1 is existing heat pump type air conditioner refrigerating and heating systems schematic diagram;
Fig. 2 is the utility model refrigerating and heating systems schematic diagram.
Omitted among the figure and other irrelevant parts of the present utility model point.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further.
As shown in Figure 2, the utility model comprises the closed circuit of being made up of compressor, low-pressure liquid storing tank, cross valve, outdoor condenser, indoor evaporator and high pressure fluid reservoir 1, the connecting line of its mesohigh fluid reservoir 1 and outdoor condenser is provided with and heats throttle part A, and the connecting line of high pressure fluid reservoir 1 and indoor evaporator is provided with refrigeration throttle part B.
The above-mentioned throttle part A that heats is formed in parallel by throttle capillary tube 2 and check valve 3.
Above-mentioned refrigeration throttle part B is formed in parallel by throttle capillary tube 4 and check valve 5.
During the utility model heat pump type air conditioner refrigeration, enter the high pressure fluid reservoir from the come out cold-producing medium of normal temperature high voltage of outdoor condenser through the check valve that heats the throttle part, because the effect of the check valve of refrigeration throttle part, throttle capillary tube from the refrigerant flow direction refrigeration throttle part that the high pressure fluid reservoir comes out, evaporimeter refrigeration in the inlet chamber after the throttle capillary tube throttling step-down in the cold-producing medium process refrigeration throttle part; When heating, the cold-producing medium reverse flow of coming out from compressor, the function of cool room external condenser and indoor evaporator " is exchanged ", the normal temperature high voltage cold-producing medium that comes out from indoor evaporator enters the high pressure fluid reservoir through the check valve of refrigeration throttle part, flow to then and heat throttle part, because heat the effect of the check valve of throttle part, cold-producing medium is through heating inlet chamber external condenser after the throttle capillary tube throttling step-down, like this, no matter system is in refrigeration still heats state, and the high pressure fluid reservoir stores high-pressure refrigerant all the time.
