Description
Technical field
This utility model relates to a kind of domestic air conditioning, particularly to a kind of domestic evaporative air conditioning system.
Background technology
Existing house and office building use domestic air conditioning to include split type or window the most in a large number, and it is air cooling air conditioner
System, the ratio of Energy Efficiency Ratio i.e. refrigerating capacity and power consumption, the biggest Energy Efficiency Ratio of coefficient of refrigerating performance is the biggest, and coefficient of refrigerating performance is the least
Energy Efficiency Ratio is the least relatively low, and the Energy Efficiency Ratio of most air-conditionings is all below 2.0, and the impact of climate condition is big,
Temperature more high energy efficiency ratio is the lowest, and particularly in summer high temperature weather, its Energy Efficiency Ratio is lower, the sky even having
Adjusting in high temperature environments cannot be properly functioning.Owing to its energy consumption is big, the noise that air-conditioning produces is also big, particularly
All open air conditioner refrigerating summer when, its noise makes a lot of people normally to fall asleep, serious shadow
Ring the physical and mental health having arrived resident.
From refrigeration principle, the compression process pressure ratio of kind of refrigeration cycle is the biggest, coefficient of refrigerating performance i.e. refrigerating capacity with
The ratio of cycle consumption net work is the least.Comparatively speaking, air cooling way is poor due to its cooling effect, cold-producing medium
Condensation temperature and saturation temperature high, corresponding saturation pressure and compressor delivery pressure are higher, compressed
Journey pressure ratio is relatively big, and coefficient of refrigerating performance is less；And water-cooling pattern is due to its good cooling results, the condensation of cold-producing medium
Temperature and saturation temperature thereof are low, and corresponding saturation pressure and compressor delivery pressure are relatively low, the pressure of water-cooling pattern
Compression process pressure ratio is less than air cooling way, and coefficient of refrigerating performance is bigger.To this end, those skilled in the art's invention
Water-cooling pattern is used to carry out air-conditioning condenser heat exchange domestic air conditioning, as China Patent Publication No. is
CN101871682A, on October 27 2010 publication date, disclosed a kind of household direct evaporation type is empty
Tune machine and off-premises station used thereof.But this kind of air-conditioning uses recirculated water to cool down mostly, needs to arrange recirculated water
, there is the defect that structure is complicated, bulky in system and such as cooling tower class circulating water cooling system.Therefore,
Need the air-conditioning of existing water-cooling pattern is further improved, to form coefficient of refrigerating performance close to water-cooling pattern
Vaporation-type cooling.
Summary of the invention
The purpose of this utility model is aiming at the deficiencies in the prior art, it is provided that a kind of domestic transpiration-cooled is empty
Adjusting, this air-conditioning utilizes condenser that cooling water is carried out heat exchange, makes cooling water vapor and side that direct evaporation falls
Formula, is not required to arrange water circulation system and circulating water cooling system, its simple in construction, and volume is little, it is adaptable to live
Residence, office's window air conditioner and split-type air conditioner.
For achieving the above object, this utility model adopts the following technical scheme that.
A kind of domestic evaporative air conditioning system, including compressor, condenser, vaporizer, expansion valve and water distribution
