Abstract
A kind of hot-gas bypass type residential central air conditioning, it comprises refrigeration system, evaporimeter and hot gas bypass valve, it is characterized in that connecting in Crew Cooling System a hot gas bypass valve, an end connected system high pressure of hot gas bypass valve, another termination evaporator, balance pipe welding system low pressure.The utility model has overcome the high frequent start and stop that cause when residential central air conditioning refrigeration system back pressure is on the low side, and the increase of power consumption or the deficiency that operational efficiency reduces during defrosting, and is simple in structure, easy for operation.
Description
Technical field
The utility model relates to a kind of hot-gas bypass type residential central air conditioning.
Background technology
At present, when residential central air conditioning refrigeration system back pressure was on the low side, processing method commonly used was to realize low-voltage variation by control system, makes compressor shutdown, and when returning to the force value of setting etc. the refrigeration system back pressure, compressor restarts again; Residential central air conditioning defrosting method commonly used is electrical heating defrosting or the defrosting of refrigeration system inverted running, and the compressor frequency start and stop easily cause compressor damage, electrical heating defrosting expense electricity, and the inverted running defrosting reduces running efficiency of system.
Summary of the invention
The purpose of this utility model is to provide a kind of hot-gas bypass type residential central air conditioning, and it can be introduced gases at high pressure from the refrigeration system high pressure end and improve the back pressure of compressor and the air-conditioning unit is carried out defrosting.
The present invention is achieved like this, it comprises refrigeration system, evaporimeter and hot gas bypass valve, it is characterized in that connecting in Crew Cooling System a hot gas bypass valve, an end connected system high pressure of hot gas bypass valve, the other end connects evaporator, balance pipe connected system low pressure.
The utility model has overcome the high frequent start and stop that cause when residential central air conditioning refrigeration system back pressure is on the low side, and the increase of power consumption or the deficiency that operational efficiency reduces during defrosting, and is simple in structure, easy for operation.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Evaporimeter 2, hot gas bypass valve 3, system low-voltage 4, system high pressure 5, refrigeration system in the drawings 1,
The specific embodiment
As shown in Figure 1, the utility model connects a hot gas bypass valve (2) in machine set system (5), an end connected system high pressure (4) of hot gas bypass valve, and an end connects evaporimeter (1) import, balance pipe connected system low pressure (3).When the air-conditioning unit was in refrigerating state, if the machine set system back pressure is on the low side, when being lower than a certain setting value, the hot-gas bypass opening of valves was communicated with the system high pressure end with evaporator, and high temperature and high pressure gas enters evaporimeter, can improve back pressure.When the air-conditioning unit is in when heating state, if unit evaporimeter frosting, cause the machine set system back pressure on the low side, when being lower than a certain setting value, the hot-gas bypass opening of valves, the system high pressure end is communicated with evaporator, and high temperature and high pressure gas enters evaporimeter, can melt the frost on the evaporimeter and improve back pressure.Like this, system's back pressure raises, and when system's back pressure was elevated to a certain setting value, hot gas bypass valve was closed.
