Description
Technical field
The invention belongs to air-conditioning heating technology field, and in particular to a kind of double low-temperature receiver fresh air conditioners of family expenses condensing units,
Hot water units.
Background technology
With developing rapidly for national economy, the quick raising of living standards of the people and outdoor air pollution are serious all the more,
People propose requirement higher to the humiture and air ambient of household.There is indoor set blower fan in original heat pump type air conditioning system
Noise is big, blowing feeling is strong, summer excessively dehumidifies and winter hot blast floats, outdoor unit bit occupancy area is big, fresh air is made by infiltration
It is not enough into resh air requirement, it is impossible to the problems such as purifying, requirement of the people to domestic environment can not have been met.Many families are above-mentioned to solve
Problem employs the scheme of multi-connected machine+floor heating+burnt gas wall hanging furnace+fresh air heat recovery ventilator.Although the program is preferably
The requirement of people's more high degree of comfort is met, but be still present that number of devices is more, utilization rate is low, cost is too high, energy consumption is larger,
Fuel gas buring discharges the problem of nitrogen oxides.
Floor radiant cooling, heating+dedicated outdoor air system are the comparatively ideal schemes for solving the above problems.But there is also needs
Dedicated outdoor air system depth is dehumidified, to ensure the problem that radiation cooling floor does not condense.And the system can not solve life
Hot water supply problem living, need to be further provided with water heater.
Be improve air-conditioning system efficiency, reduce number of devices, Chinese patent whole-year air source heat pump three-function group and
Its operation method (applying date：2010.1.28, application number：2010101039335, publication date：2010.8.11, publication number：
CN101799223A) disclose it is a kind of can be while producing the net for air-source heat pump units of hot and cold water and domestic hot-water.The unit is used
Four-way valve and the mode of solenoid valve control switching, meet the need of building entire-year air conditioner cold and hot water and domestic hot-water well
Ask.But the unit is still present following deficiency：1. the cold water that the unit in summer is produced is only single leaving water temperature, it is impossible to meet temperature
The requirement of humidity-independent control；2. the low-temperature cold water that summer produces, the temperature difference with outdoor air is larger, and its efficiency still has improvement empty
Between；3. the unit is unitary device, bulky, is only applicable to big-and-middle-sized commercial building, is not suitable for house and small-sized business
Industry；4. fresh air need in addition configure Fresh air handling units.
In order to further improve efficiency and comfort level, independent temperature-humidity control air-conditioning system of the Chinese patent with heat recovery function
System (the applying date：2014.6.5, application number：201410244116X, publication date：2014.8.20, publication number：CN103994601A)
Disclose a kind of humiture independence control air conditioner system with heat recovery function.The unit produces dual temperature respectively using double-compressor
The mode of cold water meets the requirement of summer independent temperature-humidity control, and condensation heat is collected in heat collector, is passed by heat pipe
Heat completes condensing units to hot water supply system.But the system equally exists deficiency：1. condensation heat recovery device is excessively multiple
Miscellaneous, volume is big, and cost is high；2. MCS exchanges heat twice by refrigerant-low-temperature cold water, low-temperature cold water-fresh air, device
Complexity, increases heat exchange loss；3. the system is not provided with four-way reversing valve and coolant system switch valve, it is impossible to same in the winter time
When meet the demand of heating and domestic hot-water.
Therefore, in the urgent need to it is a kind of can meet simultaneously family whole year domestic hot-water and summer fresh air dehumidification purification it is small-sized
Fresh air handining unit coordinates Miniature air-cooling heat pump water chiller-heater unit and radiation cooling, heating plate composition family expenses humiture independence
Control system, preferably to meet requirement of the people to home comfort degree.
