Abstract
The present invention discloses an arrangement method of a flow channel of a refrigeration agent of an air conditioner with a heat pump, and an air conditioner adopting the method. At least one heat exchanger of an indoor heat exchanger and an outdoor heat exchanger of the air conditioner is provided with two sets or more than two sets of pipelines of refrigeration agents, wherein the pipelines are connected in series or in parallel. The pipelines of the refrigeration agents are controlled by a pipeline switching device so as to form different flow channels of the refrigeration agents. Because the flow directions of the refrigeration agents are different in a refrigeration or heating process of the air conditioner, the number of the flow channels of the refrigeration agents when the heat exchanger is used as a condenser is smaller than that of the flow channels of the refrigeration agents when the heat exchanger is used as an evaporator through the pipeline switching device. The present invention changes the single reverse direction flow of the original refrigeration agents in a refrigeration running state and a heating running state, according to the different running states of the air conditioner, the flow channels of the refrigeration agents are distributed newly, and therefore, the present invention satisfies requirements that optimum design is respectively carried out by the air conditioner independently in the refrigeration running state and the heating running state. The present invention achieves the effects of good performance, low power consumption, high energy efficiency ratios and material saving.

Technical field
The present invention relates to a kind of refrigerant flow path method for arranging of heat pump air conditioner and adopt the air-conditioner of this method.
Background technology
Heat pump air conditioner mainly comprises indoor heat exchanger, outdoor heat exchanger, compressor, four-way change-over valve, capillary at present, it is indoor, the refrigerant flow path in the outdoor heat exchanger is changeless, when heat pump air conditioner when the refrigerating operaton state switches to the heating operation state, the cold-producing medium in the heat exchanger of indoor and outdoor only carries out reverse flow in former runner.Since air-conditioner the refrigeration with heat different operating modes under, the flow velocity of cold-producing medium, temperature, pressure are different, when adopting this heat exchanger refrigerant flow path design, can't guarantee that indoor, outdoor heat exchanger gives full play to its exchange capability of heat under different running status conditions, thereby limit the raising of air-conditioner Energy Efficiency Ratio and refrigeration (heat) amount.
Summary of the invention
The present invention overcomes above-mentioned problems of the prior art, provide a kind of function admirable the high energy efficiency heat pump air conditioner the refrigerant flow path method for arranging and adopt the air-conditioner of this method, adopt this refrigerant flow path method for arranging, make exchange capability of heat indoor, outdoor heat exchanger give full play to, improved the Energy Efficiency Ratio and refrigeration (heat) amount of air-conditioner.
The present invention adopts following technical scheme to realize: a kind of refrigerant flow path method for arranging of heat pump air conditioner, have at least a heat exchanger to be furnished with two groups or more refrigerant tubing in parallel in the indoor heat exchanger of air-conditioner, the outdoor heat exchanger, refrigerant tubing constitutes different refrigerant flow path by the pipeline switching device shifter control of series connection with it, because cold-producing medium is at air conditioner refrigerating or heat the difference that flows in the process, the refrigerant flow path number when the refrigerant flow path number when making described heat exchanger make condenser by the pipeline switching device shifter is made evaporimeter less than heat exchanger.
Preferred version of the present invention is: the refrigerant flow path quantity when described heat exchanger is done the evaporimeter use is 1.5-3 times when doing the condenser use.
Described in the present invention pipeline switching device shifter is check valve, two-bit triplet magnetic valve or their combination.
The present invention adopts the heat pump air conditioner of above-mentioned refrigerant flow path, it comprises compressor, indoor, external heat exchanger, four-way change-over valve, the changes in temperature switching device shifter, capillary, described indoor heat exchanger, have at least a heat exchanger to be provided with two groups or more refrigerant tubing that uses in parallel in the outdoor heat exchanger, on refrigerant tubing, be provided with the pipeline switching device shifter, refrigerant tubing connects and composes different refrigerant flow path through the piping switching device shifter with four-way change-over valve pipeline and capillary, the refrigerant flow path number when the refrigerant flow path number when wherein heat exchanger is made condenser is made evaporimeter less than heat exchanger.
In heat pump air conditioner of the present invention, described heat exchanger is provided with two groups and connects back refrigerant tubing in parallel with different capillaries respectively, the parallel connected end of two groups of refrigerant tubings is connected with the input of a check valve, wherein one group of refrigerant tubing is connected with the output of another check valve with the capillary link simultaneously, another end points of described two check valves is connected with the pipeline of four-way change-over valve, and above-mentioned two check valves constitute the pipeline switching device shifter.
In heat pump air conditioner of the present invention, described heat exchanger is provided with two groups and connects back refrigerant tubing in parallel with different capillaries respectively, between the parallel connected end of two groups of refrigerant tubings, one group of refrigerant tubing and capillary link, be serially connected with the control various flows to two-position three-way valve, described two-position three-way valve constitutes the pipeline switching device shifter.
Described heat exchanger is provided with two groups of above refrigerant tubings that use in parallel, and described pipeline switching device shifter is check valve, two-position three-way valve or their combination.
After adopting as above technical scheme, heat exchanger is when making condenser and use, and promptly heat exchanger is to the environment heat release, the pressure drop of flow of refrigerant is less, can improve the coefficient of heat transfer by the flow that increases cold-producing medium, thereby improve the exchange capability of heat of heat exchanger, so refrigerant flow path quantity is the least possible; On the contrary, heat exchanger is when doing the evaporimeter use, be that heat exchanger absorbs heat to environment, the pressure drop of flow of refrigerant is bigger, should suitably reduce the flow of cold-producing medium, reduce the pressure drop of flow of refrigerant, improve the mean temperature difference of heat exchanger heat transfer, thereby improve the exchange capability of heat of heat exchanger, so refrigerant flow path quantity should be many as far as possible.Refrigerant flow path quantity when in general, heat exchanger is made evaporimeter and used should be many when making condenser and use.The present invention has changed the single reverse flow of cold-producing medium under refrigeration, heating operation state in the past, and carried out the redistribution of refrigerant flow path according to the different running statuses of air-conditioner, make the exchange capability of heat of indoor and outdoor heat exchanger give full play to, improved the Energy Efficiency Ratio and refrigeration (heat) amount of air-conditioner.Test data shows, adopts above-mentioned embodiment, and the exchange capability of heat that can improve heat exchanger is more than 10%.
