Abstract

The utility model provides a working medium flow regulation device, which comprises a condenser, an evaporator and a capillary tube. The condenser and the evaporator are connected by the capillary tube. Electronic expansion valves are further connected in parallel at both ends of the capillary tube, and a working medium flow regulation device which can regulate flow automatically based on outdoor temperature changes is disposed between a condenser refrigeration working medium and an evaporator refrigeration working medium. The device reduces working medium flow inside the device when outdoor temperature is high and automatically increases working medium flow when outdoor temperature is low so as to meet different requirements for season changes and promote performance ratio of an air energy water heater.

Description

The working medium flow adjusting device
Technical field
The utility model relates to the control technology of air-source water heater working medium flow, specifically is a kind of working medium flow adjusting device.
Background technology
The heat pump compressor operating efficiency is to be controlled by the flow of cooling working medium, the working medium flow low compression ratio is little lower, refrigerating efficiency is less relatively, otherwise refrigerating efficiency is then high, certainly the work energy consumption of compression ratio higher compression machine is also higher relatively, working medium flow has high limit simultaneously, the excessive compressor internal pressure of flow is too high, then can there be potential safety hazard, in system, generally all be provided with flow regulator for this reason, prevailing flow regulator is a capillary, effect capillaceous is to keep between condenser cold-producing medium and the evaporator refrigerant certain pressure differential being arranged, to guarantee that cold-producing medium working medium has higher pressure in condenser, be condensed into liquid thereby cold-producing medium working medium is dispelled the heat in condenser; Guarantee that cold-producing medium working medium has lower pressure in evaporimeter, thereby make cold-producing medium working medium endothermic heat in evaporimeter become gas, cooling working medium is the constant speed air-conditioning inside the similar air-conditioning product that can't regulate by the capillary flow, and the Energy Efficiency Ratio of this air-source water heater is not high.
Summary of the invention
The purpose of this utility model is to provide a kind of working medium flow adjusting device, between condenser refrigeration working medium and evaporimeter refrigeration working medium, be provided with and change the working medium flow adjusting device of regulating flow according to outdoor temperature automatically, this device reduces the flow of working medium in the device when outdoor high temperature, then can strengthen the flow of working medium during outdoor low temperature automatically, adapting to the different demand of conversion in season, and promote the efficiency ratio of air-source water heater.
For achieving the above object by the following technical solutions:
A kind of working medium flow adjusting device comprises condenser, evaporimeter and capillary, and capillary is connected between condenser and the evaporimeter, it is characterized in that: the two ends thin at hollow billet also are parallel with electric expansion valve.
The utility model is parallel with electric expansion valve by the two ends of the tubule of being expert at, the electric expansion valve major advantage is accurately to control refrigerant flow, thereby reach accurate control evaporating temperature, so this working medium flow adjusting device can be regulated the flow that flows through electric expansion valve automatically according to the variation of ambient temperature, realize the automatic adjusting of working medium flow, the compressor Energy Efficiency Ratio is performed to optimal state.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of working medium flow adjusting device comprises condenser, evaporimeter and capillary 1, and capillary 1 is connected between condenser and the evaporimeter, and the two ends thin at hollow billet also are parallel with electric expansion valve 2.
The utility model in two ends capillaceous parallel connection electric expansion valve, flow wherein capillaceous can satisfy the demand for heat of air-source water heater summer high-temperature degree, electric expansion valve then can be along with conversion in season and variation of temperature are regulated the working medium flow of portion within it automatically, use the Energy Efficiency Ratio of air-source water heater to remain on optimal state, and greatly reduce the energy consumption of air-source water heater.
