Abstract

The invention provides a hot-water and floor-heating combined air-conditioning system, which consists of an outdoor machine and an annular shell and tube heat exchanger, wherein the annular shell and tube heat exchanger comprises a hot-water heat exchange coil and a floor-heating heat exchange coil. Therefore, hot water and floor heating water can be independently supplied completely by a single fluorine side. Moreover, because two indoor systems share the same outdoor machine, the system has the characteristics of low cost, simple structure and the like.

Description

A kind of hot water and floor heating hybrid a/c system

Technical field

This patent belongs to refrigerated air-conditioning system and forms, and particularly has the air-conditioning system of floor heating, health hot water function, belongs to refrigeration and field of air conditioning.

Background technology

The geothermal heating system is a heating system the most comfortable in the world at present, healthy and that popularize day by day.There is the expert to think that geothermal heating has certain function of health care.The traditional Chinese medical science is often said " people earlier warm warm leg ", people feel cold in, often be from foot and shank at first.This is because pin is centrifugal dirty place farthest, is in sanguimotor tip, a little less than the circulation of foot.The rule of adding the Nature is that hot-air is upwards soaring, and cold air is downward sink-float, so in the winter of cold, people tend to feel lower limb numbness, and very ice-cold cold." ten thousand diseases are come from pin " simultaneously, foot is the abundantest place of tip of human nerve, also is the most concentrated place of human acupoint, generation or deterioration that legs and feet are suffered from cold and can be caused various diseases

The floor heating advantage has 2 points, and the one, the heating form changes the benefit bring, owing to transfer to undergroundly, has made things convenient for and has arranged short window, and buildings such as French window have solved the heating problem of large space, large span.The 2nd, the energy-conservation and utilization of resources advantage that adopts the low-temperature water heating heating to be brought.

Ground radiation heating is stipulated that by the 5.3.7 in " energy Saving Design of Residential Buildings standard (exposure draft) " of issue on August 14th, 2007 of nation-building portion indoor area is more than or equal to 80m ²The time, should adopt the low temperature ground radiation heating system.When adopting the low temperature ground radiation heating, supply water temperature should not surpass 55 ℃, and the confession/backwater design temperature difference should not be less than 10 ℃.

In addition, Teat pump boiler is a contrary Carnot cycle principle of utilizing heat pump, and the temperature difference heat absorption by cold-producing medium and outside air, the compression of compressor heat and the processes such as lasting heat exchange of cold-producing medium and water, and water is heated.Compare with conventional water heaters, it has the following advantage Teat pump boiler: the security of Teat pump boiler: conventional water heaters is with combustion gas, electricity and solar energy are main, three minutes all over the world, the gas heater security is relatively poor, insufficient and the hydraulic pressure instability of burning easily causes combustion gas poisoning and scald incident, the electric leakage hidden danger and the dwelling house imperfect earth of electric heater also cause serious threat to consumer's life security, the characteristics of solar water heater water-storage formula have determined it when fine day, water temperature may be very high, cause scald, the auxiliary heating of overcast and rainy electricity but stays potential safety hazard, different with above water heater, the Teat pump boiler process of heating is to add water in the hot-water cylinder by the high-temperature high-pressure refrigerant gas that compressor is discharged, electricity is mainly used in compressor, gas after heating is by the coil pipe of outer disc type and the water heat-shift in the enamel water pot, water power separates fully, like this, neither there is electric leakage hidden danger, saved anti-creeping worry, also avoided electric heating tube surface temperature height, easily fouling and influence the drawback of the efficiency of heating surface is really accomplished to be perfectly safe.

And such two kinds of hot water are to use with at same system, are not meet hygienic requirements on the one hand, and in addition, the temperature of health hot water demand is also inconsistent with floor heating water.

Summary of the invention

The present invention just provides a kind of hot water and floor heating hybrid a/c system, it is made up of off-premises station and a circular casing heat exchange of heat pipe, the latter comprises hot water heat exchange coil and floor heating heat exchange coil, so just realized that by single fluorine side hot water and floor heating water fully independently supplies, and because two shared same outer machines of indoor heating system, system has low cost, characteristics such as simple in structure.

The technical scheme that the present invention solves the problems of the technologies described above employing is, adopt such air-conditioning system, it is made up of off-premises station and a circular casing heat exchange of heat pipe, the latter comprises hot water heat exchange coil and floor heating heat exchange coil, when hot water has demand, start the hot water water pump, interior machine controller transmission hot water demand and temperature requirement are to outdoor controller; When floor heating has demand, start the floor heating water pump, interior machine controller transmission floor heating demand and temperature requirement are to outdoor controller.

The specific embodiment

Health hot water:

When hot water has demand, start the hot water water pump, make the interior water of coil pipe have corresponding boiler to circulate, interior machine controller sends the hot water demand to outdoor controller, and design temperature requirement, as the health hot water setting value is 55 degree, and outer machine is given the circular casing heat exchange of heat pipe according to the signal output refrigerant or the adjusting coolant quantity of interior machine controller; When the hot water temperature reaches 55 degree, stop hot water water pump and off-premises station.

Floor heating:

When the user starts floor heating, start the floor heating water pump, the interior water of coil pipe is had in the corresponding floor heating loop to circulate, interior machine controller sends the floor heating demand to outdoor controller, and design temperature requirement, as floor heating hot water setting value is 45 degree, be lower than 45 degree as the floor heating leaving water temperature, and outer machine is given the circular casing heat exchange of heat pipe according to the signal output refrigerant or the adjusting coolant quantity of interior machine controller; When the floor heating hot water temperature reaches 45 degree, stop off-premises station.
