Abstract
The utility model relates to a virtual evaporation air-cooled cold and hot water unit, which is characterized in that an evaporator is connected with a regenerator; the regenerator is connected with a gas-liquid separator; the gas-liquid separator is connected to a compressor; the compressor is connected with a condenser; the condenser is connected with the regenerator; the regenerator is connected with an expansion valve; the expansion valve is connected with the evaporator. By adopting the virtual evaporation air-cooled cold and hot water unit provided by the utility model, the existing defects that the evaporation area is severely reduced and a heating effect is influenced due to the fact that the required area of an evaporator coil reaches up to 15-20 percent in order to provide a superheat degree of 5 degrees to prevent the liquid impact of the compressor at low temperature or severe frosting in the prior art are overcome. According to the virtual evaporation air-cooled cold and hot water unit provided by the utility model, the superheat degree is provided by the regenerator, and on the premise that the superheat degree is still set to be 5 degrees, the heat exchange area of the evaporator coil originally used for providing the superheat degree of 5 degrees can be used for evaporation. The virtual evaporation air-cooled cold and hot water unit has the effect that the evaporation area is increased by 15-20 percent, so that the evaporation temperature is increased and the refrigerant mass flux is increased.
Description
Technical field
The utility model relates to air-source and heats technology, particularly virtual evaporating air-cooling hot and cold water unit.
Background technology
Before the present utility model, a defect of air-source heating machine set is that evaporating temperature and pressure are low especially, cause frosting more severe, form vicious circle when low temperature or serious frosting.During this time, in order to provide the degree of superheat of 5 degree to prevent that compressor liquid is long-pending, the evaporator coil area needing, up to 15-20%, so seriously reduce disengagement area, affects heating effect.And traditional regenerator is to utilize regenerator simultaneously overheated after cold-peace, evaporimeter is still wasted coil heat exchange area provides 5 to spend temperature.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned defect, develops virtual evaporating air-cooling hot and cold water unit.
The technical solution of the utility model is:
Virtual evaporating air-cooling hot and cold water unit, its technical characteristics is that evaporimeter connects regenerator, regenerator connects gas-liquid separator, gas-liquid separator is connected to compressor, and compressor connects condenser, and condenser connects regenerator, regenerator connects expansion valve, and expansion valve is connected to evaporimeter.
The utility model utilizes regenerator to provide 5 to spend temperature, the 15-20% evaporator coil area of waste is used for evaporating, thereby the runnability that promotes evaporating temperature, increase refrigerant mass flow and enhancing compressor, utilizes regenerator to liberate the evaporator coil area of 15-20%.
The utility model utilizes regenerator that the degree of superheat is provided, and the degree of superheat is still being arranged in the prerequisite of 5 degree, originally for providing the 5 evaporator coil heat exchange areas of spending temperature just can be for evaporation.Concrete effect is that disengagement area has strengthened 15-20%, so promote evaporating temperature and increase refrigerant mass flow.
Also has in addition refrigerant evaporation and excessively cold simultaneously in regenerator.Concerning compressor, all what before air intake duct, absorb heat is all evaporimeter, and any what after blast pipe, dispel the heat is all condenser.In such event,, concerning compressor, regenerator is to have strengthened evaporimeter and condenser simultaneously.Because the condensation temperature of hot and cold water unit depends on hot water temperature, so only have evaporating temperature to promote, condensation temperature does not reduce, thereby compressor behavior and heat all get a promotion.
Advantage of the present utility model have following some:
1. frosting is delayed and is lacked: the unit of patent of the present invention, and utilize regenerator 5 degree temperatures are provided and virtual evaporation is provided, can promote evaporating temperature 1.5 degree.The lifting postponement heat pamp of evaporating temperature and minimizing frosting degree, the evaporator section simultaneously increasing is virtual and frost-free, so the whole frosting of unit is delayed especially and lacks.
2. promote low temperature and high wet cooling condition heating capacity: regenerator provides 5 heats of spending temperature, thereby the coil pipe disengagement area of liberation 15-20%, so heating capacity promotes.
3. improving low temperature and high wet cooling condition heats state and expands heating operation scope: because utilize regenerator that the coil pipe of the 15-20% of waste is used for evaporating, improved evaporating temperature, refrigerant mass flow increases, so the running status of compressor is improved, unit can be in worse operating mode operation.
Other concrete advantages of the present utility model and effect will go on to say below.
Accompanying drawing explanation
Fig. 1---the utility model structural principle schematic diagram.
In figure, each label represents that corresponding component names is as follows:
Regenerator 1, gas-liquid separator 2, evaporimeter 3, expansion valve 4, condenser 5, compressor 6.
The specific embodiment
Technical thought of the present utility model is:
The utility model utilizes regenerator to provide over 5 heats of spending temperature, so just can vacate the disengagement area of 15-20%, promotes evaporating temperature and pressure.
As shown in Figure 1:
The explanation of the utility model application process:
When refrigerant enters into regenerator 1 from evaporimeter 3, utilize regenerator 1 to provide and surpass 5 heats of spending temperature, the coil pipe disengagement area of liberation 15-20% is for evaporation, and part refrigerant evaporates in regenerator 1 simultaneously, improves evaporating temperature and increases refrigerant mass flow.
When refrigerant flows out and enters compressor 6 from regenerator 1, concerning compressor 6, condensation in regenerator 1 and evaporation are all actual, so condenser 5 and evaporimeter 3 corresponding to compressor 6 have all increased, so evaporating temperature promotes condensation temperature, depend on that hot water temperature remains unchanged, result is that evaporating temperature and compressor behavior all further get a promotion.
Refrigerant flows out and enters condenser 5 from compressor 6, then enters regenerator 1, then through expansion valve 4, gets back to evaporimeter 3.
At low temperature or how white state heating operation, the fatal problem that unit faces is evaporating temperature and hypotony, so frosting state is just more severe, forms vicious circle.In this severe situation, regenerator 1 just plays the effect of directly improving compressor 6 running statuses.Evaporating temperature promotes, and not only frosting is few, meanwhile, because the present invention has liberated the evaporator coil of 15-20% for evaporation, thus the not minimizing of overall heating capacity, but increased.
