Description

A kind of instant-heating formula dual intensity Teat pump boiler and its implementation
Technical field
The present invention relates to Teat pump boiler technical field, specifically refer to a kind of instant-heating formula dual intensity Teat pump boiler and its implementation.
Background technology
At present, the air source hot pump water heater being comprised of air source heat pump and boiler is widely used.Between air source heat pump and water tank, by a circulating pump, realize from water tank extraction cold water to heat pump and heating.Water heat exchanger, compressor, gas-liquid separator, evaporimeter, expander, device for drying and filtering that air source heat pump mainly comprises shell and is installed in enclosure.Wherein, water heat exchanger adopts double pipe heat exchanger more, and in double pipe heat exchanger, a kind of fluid (common is water) is walked in pipe, and one other fluid (common is refrigerant) is walked annular space.The operation principle of above-mentioned air source hot pump water heater is as follows: in water tank during lack of water, cold water directly supplements inlet water tank, when Water in Water Tanks Wen Wei reaches preset temperature and need to heat, cold water in water tank enters the water heat exchanger of air source heat pump through circulating pump, compressor obtains driving force after electric energy input, and refrigerant is absorbed airborne Low Temperature Thermal gasification, after gas-liquid separator is processed by overcompression machine, become high temperature refrigerant by evaporimeter; High temperature refrigerant is transported in the refrigerant pipe of double pipe heat exchanger by total refrigerant exit of air source heat pump, and high temperature refrigerant leads to heat transfer, and heating is positioned at the water of inside pipe casing; Finally, heated water is filled with to boiler by conveyance conduit, and by device for drying and filtering, expander, is obtained and recycled with this from the low temperature refrigerant of double pipe heat exchanger output; When water, water route is connected in the supply-water pump pressurization operation of water tank, draws hot water to using water end (W.E.) from water tank, and the hot water of drawing from supply-water pump, except leading to water end (W.E.), also supplements backwater in recovery tank by pipeline.
Above-mentioned air source hot pump water heater is the directly-heating type water heater of single cycle high-temperature heat accumulation, has the following disadvantages:
1, in above-mentioned existing air source hot pump water heater, owing to adopting single air source heat pump heating, summer water temperature requirement lower, while only exceeding several degrees Celsius than room temperature even, (while injecting as cold water, water temperature is not 25 °, temperature requirement value is 32 °), as adopting air source heat pump to carry out FCL when heating to the hot water in water tank, temperature speed is low, so that or need to wait for that the regular hour can reach the hot water of supply satisfied temperature requirement value
2, when water temperature requirement is higher, as more than 40 °, because mode of heating is single drawn water heating and be directly back in water tank from water tank by air source heat pump, during water, supply-water pump pressurization directly exports the hot water in water tank to water end (W.E.), and because supply channel is conventionally longer, hot water leads to this section of pipeline of water end (W.E.) and can cause water temperature to reduce from water tank, because lack temperature supply in this section of water pipeline, this just makes the hot water in water tank need to reach for a long time higher storage temperature.In physical principle, same temperature rise value, initial water temperature is higher, the power consumption of air source heat pump is just larger, and the refrigerating capacity of air source heat pump is just less, so, the mode of existing directly-heated type single cycle high-temperature heat accumulation, the heat exchanger effectiveness of air source heat pump is low, and the medium-term and long-term high temperature retaining of water tank is because of larger with the environment temperature temperature difference, and thermal losses is also large; When water tank lacks water, cold water is directly to fill into water tank, cause thus in water tank original hot water temperature to assign amplitude larger, in the situation that this water heater only adopts air source heat pump to carry out single heating, cause the water needs longer time in water tank can reach water outlet requirements.
In sum, existing air source hot pump water heater, because it adopts the heat pump single cycle mode of heating for the treatment of instrument, causes firing rate slow, and heat exchanger effectiveness is low, can not meet the demand of people to water heater open-and-heating.
