Description
Technical field
The utility model relates to a kind of heat pump energy-conserving system.
Background technology
Heat pump techniques is a kind of new energy technology that receives much attention in the whole world in recent years." pump " that people were familiar with is a kind of plant equipment that can improve potential energy, mainly is that water is extracted into a high position from low level such as water pump.
And " heat pump " is a kind of low grade heat energy that can obtain from natural air, water or soil, and through the electric power acting, providing can be by the device of the used high-grade heat energy of people.It transfers to high temperature heat source with the heat energy of low-temperature heat source, it is medium---air, river, the seawater of ours on every side that the low-temperature heat source that is generally used for heat pump assembly changes, or the working medium of from the equipment of industrial product, discharging, the normal and surrounding medium of these working medium has the temperature that is close.
The operation principle of heat pump assembly is consistent with compression refrigerating machine, when heat pump assembly was pressed the cooling condition operation, the high steam by compressor is discharged entered condenser through reversal valve (claiming cross valve again), refrigerant vapour is condensed into liquid, enter evaporimeter through throttling arrangement, and in evaporimeter, absorb heat, room air is cooled off, refrigerant vapour after the evaporation, behind reversal valve, sucked, go round and begin again like this, realize kind of refrigeration cycle by compressor.Need to realize heating function, then earlier reversal valve is turned to the heat pump operating position, the high pressure refrigerant vapor of discharging then by compressor, behind the commutation Yan, flow into indoor evaporator (making condenser uses), the latent heat of emitting during the refrigerant vapour condensation, room air is heated, reach the heating of house purpose, condensed liquid refrigerant, cross throttling arrangement from reverse flow and enter condenser (making evaporimeter uses), absorb external heat and evaporate, the steam after the evaporation is sucked by compressor through behind the reversal valve, finishes heating circulation.Like this, the heat " pump " in the outside air (or recirculated water) is gone into higher indoor of temperature, so be called " heat pump ".
The Teat pump boiler kind is a lot of in the market, mainly contains solar energy boosting type, the three kinds of series in water source and air source.Solar energy assisted heat pump is a kind of heat pump techniques that heat pump is used in combination with heliotechnics; Water resource heat pump is that the water source (more than 20 ℃) that utilizes uniform temperature is media with the cold-producing medium as thermal source, with the heat absorption in the water source after compressor compresses heat, to reach heating and to produce the purpose of hot water, water resource heat pump must have the water source of uniform temperature and flow by heat exchanger and cold water heat-shift; Air source heat pump obtains heat with the water resource heat pump similar approach from air and adds hot water.In three kinds of heat pumps, the condition restriction minimum that air source heat pump is subjected to, development space maximum.
The basic principle of Teat pump boiler: it mainly is made up of compressor, heat exchanger, aerofoil fan, attemperater, water pump, fluid reservoir, filter, electric expansion valve and electronic automatic controller etc.After connecting power supply, the aerofoil fan entry into service, outdoor air carries out heat exchange by evaporimeter, air after temperature reduces is discharged system by fan, the vaporization of the working medium of evaporimeter inside heat absorption simultaneously is inhaled into compressor, compressor is compressed into high temperature with this low pressure working fluid gas, gases at high pressure are sent into condenser, also passed through condenser by the water of water pump forced circulation, sent to for the user after the working medium heating and used, and working medium is cooled into liquid, this liquid inflow evaporator once more after expansion valve throttling cooling, periodic duty so repeatedly, heat energy in air is delivered in the water by constantly " pump ", water temperature in the attemperater is raise gradually, reach at last about 55 ℃, just in time be fit to people's bathing, the basic functional principle of Here it is air source hot pump water heater.

The air source heat pump heat-transfer working medium is a kind of particular matter, and its boiling point is subzero 40 ℃ under the normal pressure, and freezing point is subzero below 100 ℃, and this material is a liquid in the time of cold, but is easy to be evaporated into gas, and vice versa.Therefore in actual motion, the evaporation limiting temperature of heat-transfer working medium is subzero about 20 ℃ in the air source heat pump, and 5 ℃ environment temperature also is " heat " to low temperature like this, even snowy temperature, such as 0 ℃, also be hot by contrast, therefore, still commutative heat energy.
When people use heat pump usually, only be its heating of single utilization or refrigerating function, and find not utilize simultaneously its heating and refrigerating function.In the actual life,, also need refrigerating function no matter winter or summer had often both needed heating function.Become the electrical equipment that throughout the year is not related to such as refrigerator in the family, and water heater equally also is an electrical equipment that throughout the year is not related to.Some zone of same a lot of factories need provide heat, and other zones then need heat radiation.
