Background technology

Airborne steam carries a large amount of heats, particularly in south, even in the winter time, be positioned at the more acceptance of equatorial earth surface solar radiation give raising by amount temperature of the earth, heat energy rises to atmosphere with long wave reflection and moisture heat absorption evaporating course and generates the warm moist air layer, the warm moist air layer constantly flows to the low direction to the north pole of temperature again and also weakens gradually, has contained the unlimited low level heat source by conversion of solar energy in the air in this regional extent that flows.Through statistics, ambient air temperature is that 2～5 ℃ duration is about 40 days, accounts for winter low temperature high humidity weather more than 85%, about about 10 days of cumulative time when ambient air temperature is lower than below 1.5 ℃.

At present, water source, Di Yuan, air source heat pump technology are widely used in hotel, hotel, school, industrial enterprise.Its system obtains low-temperature heat source by natural energy (water, air, thermal regenerator), becomes high temperature heat source after the system high efficiency thermal-arrest is integrated, and is used for hot-water supply, and whole system collecting efficiency height has obtained using widely.Yet, traditional water source, Di Yuan, air source heat pump technology all exist certain bottleneck, restricting the broad development of this technology, as: traditional water resource heat pump needs digging well to get water, and most of regional geology structural condition complexity causes and can utilize the space limited, and the various places water condition has nothing in common with each other, well water constant temperature instability, the restriction Energy Efficiency Ratio, and also can cause pollution of waterhead; Earth source heat pump is because of the needs tubing that picks up, and various places geological conditions difference causes cost of investment high; Present existing air source heat pump needs the big different transfer of heat in arrowband, when ambient air temperature reduces in the winter time, especially ground such as Hunan, Jiangxi, Yunnan, Guizhou, Sichuan, the heat pump Energy Efficiency Ratio extremely reduces, and can there be icing, frosting phenomenon, make the heat pump can't operate as normal, can only be aided with fuel Heating and keep the hot water supply.

Summary of the invention

The utility model provide a kind of can effectively solve freeze easily in air source heat pump winter, frosting and cause the heat-pump water heater that can't normally use problem.

The utility model water resource heat pump hot water apparatus comprises heat exchange columns, the thermal source pump, evaporimeter, compressor, expansion valve, condenser, heat-exchanger pump, accessory and accessory connecting pipes each other such as boiler, heat exchange columns wherein is by the carbonated drink separating layer, the anti-heat exchange layer that floats, aluminium foil heat exchange layer, negative temperature spray concentration systems is formed, the thermal source pump forms circulation by thermal source pipeline and heat exchange columns and is connected, compressor is connected with expansion valve formation circulation by heating pipeline, heat-exchanger pump forms circulation by the hot water line with boiler and is connected, described heat exchange columns is by the carbonated drink separating layer, the anti-heat exchange layer that floats, aluminium foil heat exchange layer, negative temperature spray concentration systems composes in series, flow media enters the carbonated drink separating layer of heat exchange columns successively by the thermal source pipeline from the thermal source pump, the anti-heat exchange layer that floats, aluminium foil heat exchange layer, after the negative temperature spray concentration systems, receive the thermal source pump again through behind the evaporimeter, form the work loop of circulation.

Above-mentioned evaporimeter is thermal source pipeline and the exchange heat environment that heats pipeline, condenser is the exchange heat environment that heats pipeline and hot water line, heat pipeline and link to each other successively with compressor outlet, condenser, expansion valve, evaporimeter, compressor inlet respectively, form the work loop of circulation; The hot water line links to each other successively with boiler outlet, heat-exchanger pump, condenser, boiler import respectively, forms the work loop of circulation.Flow media in the thermal source pipeline is a heat exchange recirculated water, and the flow media that heats in the pipeline is a cold-producing medium, and the flow media among the hot water line is a high-temperature-hot-water.

With respect to resource-hungry heat-obtaining modes such as fuel oil, fire coal heat, the utility model thermal source derives from the steam of nature, does not have the problem of Air and resource consumption; With respect to water resource heat pump,, effectively protected water resource not contaminated owing to do not need digging well to get water; With respect to earth source heat pump, do not need to solve geological conditions, the problem of the pipe laying that picks up, cost of investment; With respect to common in the past air source heat pump; solved because of the normal problem of heat supply of freezed in winter, frosting; as long as a spot of high-order electric energy of input; just can realize that Lowlevel thermal energy shifts to high level heat; effectively saved the energy; greatly protect ecological environment, saved construction cost and management cost simultaneously.
