Abstract
The open capillary radiation cold supply system based on chlorofluoromethane refrigerant of the utility model.The technical solution of the utility model is that capillary radiation plate regards a part of the evaporator as refrigerant system as, and very strong Ceramic Composite undertakes room load as the radiation top plate of interior with wettability power.Capillary and highly hygroscopic 104 top disposed within of ceramic clad plate are radiated as shown in the figure, refrigerant 105 compresses after the heat in composite plate 104 in flowing absorption chamber into compressor 101, refrigerant after compression, which enters in condenser 102, to be condensed, by expansion valve 103, finally enter and absorbed heat in indoor composite plate 104, complete one cycle.The capillary radiation refrigeration system is different from the existing capillary refrigeration system of in the market, this refrigeration system is that refrigerant direct gasification in capillary is absorbed heat, compared with the energy consumption for the compressor to be saved that absorbed heat indirectly by chilled water in the market capillary and the initial cost of reduction system.Highly hygroscopic ceramics can control indoor relative humidity, improve the comfort level of human body.
Description
Technical field
The present invention relates to the radiation cooling system directly evaporated in capillary using freon.
Background technology
The current building energy consumption in China accounts for the 30% of whole society's energy consumption, and 65% that air conditioning energy consumption accounts for building energy consumption is left
The right side, and show elevated situation year by year.Part throttle characteristics influence of the air conditioner load on power network is huge, controls the energy consumption of air-conditioning and carries
The Energy Efficiency Ratio of high air-conditioning, it is to solve electric load peak-valley difference, control electric power installed capacity and realize that the energy-conservation of coal power generation link subtracts
One of important measures of row.The air-conditioning main purpose of hot summer and warm winter region is refrigeration, in refrigeration systems, it is assumed that condensation temperature is protected
Hold constant, the coefficient of refrigerating performance of refrigeration system can be significantly improved by improving the evaporating temperature of evaporator inner refrigerant, improve kind of refrigeration cycle
Performance.Air-conditioning is fixed equipment, which occupies the space in room, have impact on the space availability ratio of interior and attractive in appearance.
Radiation cooling air-conditioning system carries out heat exchange mainly by radiation mode, and heat exchange efficiency is high, radiates plate surface and interior
Uniformity of temperature profile, vertical temperature-difference gradient be small, without temperature dead angle, Blower-free noise, do not produce blowing feeling, be room generally acknowledged in the world
Interior level of comfort highest air conditioning terminal system.In addition, the system saves space, flexible arrangement, easy for installation；Each room
Between use alone cycle structure, be easy to household control, household metering；Light weight, long lifespan, health environment-friendly.Using radiation cooling
When, indoor design temperature can improve 0.5~1.5 DEG C, and radiation cooling average surface temperature only needs control at 17~19 DEG C.
Hot summer and warm winter region category subtropical climate area, the water capacity of air are higher.During using radiation cooling, its refrigerating capacity
Limited by air dew point, when radiant panel surface temperature is less than room air dew-point temperature, dew condensation phenomenon can be produced.Using height
Moisture absorption ceramic building material is combined with radiation cooling, can control radiant panel surface sweating problem well.
The content of the invention
The purpose of the present invention is to improve the space availability ratio and sanitary condition in room of the hot summer and warm winter region based on cooling,
The expense of air-conditioning equipment initial cost and day-to-day operation is reduced, builds green building.The technical program is used based on radiation
Cooling mode, indoor end equipment be capillary and highly hygroscopic Ceramic Composite into radiation top plate, be positioned over underfloor on interior,
The capillary radiation top that chlorofluoromethane refrigerant is got in by expansion valve throttling into the refrigerant air-liquid two-phase mixture of low-pressure low-temperature
Plate enters outdoor compressor after being evaporated heat absorption, the refrigerant superheat steam of HTHP is compressed into, afterwards into condenser
The refrigerant liquid of high normal pressure and temperature is condensed into, then enters capillary radiation top plate after expansion valve reducing pressure by regulating flow and completes once to make
Refrigerant cycle.
Capillary radiation cold supply system of the invention based on chlorofluoromethane refrigerant, indoor end heat transmission equipment use capillary
With the radiation top plate of highly hygroscopic Ceramic Composite, what is flowed in capillary is refrigerant air-liquid two-phase mixture, and interior is straight using refrigerant
Gasification heat absorption is connect, improves indoor design temperature and sanitary condition, is chilled water with the market flow in capillary tube, is used
The method of indirect refrigeration is compared, and such a method reduces the energy consumption of compressor and the initial cost of system, has been reached and has been saved the energy
Purpose.By using the relative humidity in highly hygroscopic ceramic control room, solves the problems, such as indoor composite surface condensation.Capillary
Pipe is made using copper metal material, is pasted, reduced between capillary and ceramics with high conductivity material between high-hygroscopicity ceramics
Heat transfer resistance.

Embodiment
Capillary radiation cold supply system of the invention based on chlorofluoromethane refrigerant, specific embodiment is referring to Fig. 1, radiation
Capillary and highly hygroscopic ceramic clad plate 104 upper floor bottom disposed within, chlorofluoromethane refrigerant 105 flow in composite plate 104
Enter outdoor compressor 101 after heat in dynamic absorption chamber to be compressed, the refrigerant superheat of the HTHP after compression is steamed
Vapour, which enters in outdoor condenser 102, to be condensed, and is condensed into the refrigerant liquid of normal temperature high voltage, by the reducing pressure by regulating flow of expansion valve 103,
Become the gas-liquid two-phase cold-producing medium of low-temp low-pressure, enter back into the radiation capillary of interior with entering in highly hygroscopic ceramic clad plate 104
Row heat absorption, completes one cycle.Capillary 201 and the front view of highly hygroscopic ceramic 203 composite plate 104 are referring to Fig. 2, capillary
Be bonded using highly heat-conductive material 202 between 201 and highly hygroscopic ceramic 203, surface brushes one layer and plasters 204 again, the material of capillary 201
For copper.Compound radiation cold plate 104 undertakes the sensible heat load of interior.
The operation principle of the present invention can be described with reference to the drawings as follows：
During summer, to ensure the comfort level in room, capillary 201 of the refrigerant air-liquid two-phase mixture 105 in composite plate 104
