Abstract
The utility model relates to a throttle control device of a heatpump or an air conditioner unit. The utility model aims at providing an improved capillary tube control structure of the heatpump or air conditioner unit, which is characterized in that the amount of the throttle of the capillary tube can be adjusted randomly with a higher energy efficiency ratio. The technic proposal of the utility model is as follows: the throttle device of the heatpump or air conditioner unit comprises a capillary tube unit, which is arranged in a pipeline between a water tank of the heatpump unit and an evaporator, or arranged in the pipeline between a condenser of the air conditioner and the evaporator. The capillary unit comprises three distributary pipelines arranged in parallel, and each distributary pipeline is formed by a capillary tube and an electromagnetic valve connected in series. The capillary unit is connected in parallel with an subbranch pipeline of an unloading valve.
Description
Technical field
The utility model relates to the throttle control device of a kind of heat pump or air-conditioning unit.
Background technology
Mostly existing source pump or air conditioner are to adopt capillary control amount of restriction when heating; Perhaps adopt double capillary, decide the break-make of second capillary by environment temperature.Not too reasonable when controlling amount of restriction capillaceous with upper type, because amount of restriction capillaceous also is subjected to the influence of water temperature height.In water temperature not simultaneously, the required refrigerant flow of system is different, and this also just needs capillary to satisfy the needs of system with different amount of restriction.But existing single capillary or double capillary control mode still can not be accomplished this point.
The utility model content
The purpose of this utility model provides the improvement of the capillary control structure of a kind of heat pump or air-conditioning unit, and it should be able to overcome the deficiency of above-mentioned background technology, but has capillary section flow regulated at will, the characteristics that Energy Efficiency Ratio is higher.
The technical solution adopted in the utility model is: the throttling arrangement of heat pump air conditioner unit, comprise the capillary group, this capillary group is installed in the water tank and the pipeline between the evaporimeter of source pump, perhaps be installed in the condenser and the pipeline between the evaporimeter in the air conditioner, described capillary group comprises three branch pipelines that are arranged in parallel, and every branch pipeline forms by a capillary and a magnetic valve serial connection.
Described capillary group also is parallel with a unloader and divides pipeline.
Operation principle of the present utility model is: when the water temperature in the water tank was low, three more cold-producing mediums of capillary output of controller opens were accelerated to heat speed to improve water temperature as early as possible; When the water temperature in the water tank is higher, can only open a capillary, close all the other two capillaries and unloaders, reduce the speed that heats; When the water temperature in the water tank water temperature lower and higher between when changing, then open two capillaries according to setting in advance; So can regulate the size of refrigerant flow more accurately.
Because the utility model has installed three capillarys that are arranged in parallel additional and has divided pipeline pipe and a unloader to divide pipeline, just can accurately regulate the amount of restriction of cold-producing medium behind the adapted controller as required.Can either obtain higher Energy Efficiency Ratio and heat speed when environment temperature is low in winter, can when summer, environment temperature was higher, also obtain higher Energy Efficiency Ratio again, and guarantee the normal operation of system.
Description of drawings
Fig. 1 is a main TV structure schematic diagram of the present utility model.
Fig. 2 is that the utility model is installed in the structural representation in the source pump.
The specific embodiment
As shown in Figure 2, this capillary control structure, be provided with capillary group 4 and corresponding controller, wherein capillary group 4 is installed in the heat exchanger 2 and the pipeline between the evaporimeter 5 of source pump (perhaps being installed in the condenser and the pipeline between the evaporimeter in the air conditioner), and the water in the water tank 1 then obtains heat from heat exchanger 2.Connect capillary group 4 by the pipeline that compressor 7 is drawn by heat exchanger 2, liquid storage cylinder 3 backs, and draw after pervaporation device 5 is back to compressor, constitute closed circuit from capillary group 4.Also have evaporator fan 5-1, vapour liquid separator 6 among the figure.
Fig. 1 as can be known, this capillary group comprises three branch pipelines that are arranged in parallel, each divides pipeline to be serially connected with a capillary and a magnetic valve.Wherein capillary 4-1 and magnetic valve 4-8 series connection, capillary 4-2 and magnetic valve 4-7 series connection, capillary 4-3 and magnetic valve 4-6 series connection; This capillary group also is parallel with a branch pipeline that is connected to unloader 4-5.The setting in advance of controller basis is controlled opening or closing of magnetic valve 4-8, magnetic valve 4-7, magnetic valve 4-6 respectively in different environment temperatures and water temperature (being determined by each signal of sensor in the system).Unloader 4-5 opens off-load with protection system safety when pipeline inner pressure is increased to high pressure conditions.
Described controller and sensor are the prior art equipment, and directly outsourcing obtains.
Arrow among the above-mentioned figure is represented the flow direction of cold-producing medium in pipeline.
Claims (2)
1, the throttling arrangement of heat pump air conditioner unit, comprise capillary group (4), this capillary group is installed in the water tank (1) and the pipeline between the evaporimeter (5) of source pump, perhaps be installed in the condenser and the pipeline between the evaporimeter in the air conditioner, it is characterized in that described capillary group comprises three branch pipelines that are arranged in parallel, every branch pipeline forms by a capillary and a magnetic valve serial connection.
2, the throttling arrangement of heat pump air conditioner unit according to claim 1 is characterized in that described capillary group also is parallel with a unloader and divides pipeline.
