Description

The solar air source heat pumps hot water apparatus

Technical field

The utility model relates to a kind of heat-pump water heater, more particularly, relates to a kind of with the solar air source heat pumps hot water apparatus of solar energy as main supply power supply.

Background technology

Be accompanied by development and national economy and more and more serious world energy sources crisis, energy-conservationly mentioned a very important position.In recent years, be accompanied by the continuous development of heat pump techniques, heat-pump water heater also develops rapidly.Under the same conditions, the power consumption of heat-pump water heater only is 1/3 to 1/4 of an electric heater, and therefore, its energy-saving potential is huge.Because the energy-efficient characteristic that heat-pump water heater had, therefore, it is saves energy greatly, and can remedy inadequate natural endowments such as the existing low-density of solar water heater, discontinuity and unstability; It is a kind of round-the-clock energy-saving and environmental protection formula hot water machine, and it is with high content of technology, and development potentiality is big, and Commercial Prospect is wide, to promoting that national economy sustainable development has great far-reaching social effect, must become the main force of following water heater.

Heat pump is a kind ofly can obtain low level heat from natural air, water or soil, and through the electric power acting, output can be by the equipment of the used high-grade heat of people.Heat pump by low-temperature heat source (as the natural air of surrounding environment, underground water, river, seawater, sewage etc.) heat absorption can, be converted to the higher temperatures thermal source then and be released in the required space (or other zone).It is the heating and the hot water facility of a kind of energy-saving and environmental protection, cleaning, and heat pump techniques is the new energy technology that receives much attention in the whole world in recent years.

Heat pump assembly both can be used as heat supply heating equipment, can be used as refrigeration cool-down equipment again.Wherein, the power conversion of the source pump of heat pump assembly, it is the effect that utilizes its compressor, by consuming certain auxiliary energy (as electric energy), under the acting in conjunction of the cold-producing medium that in compressor and heat-exchanger rig, circulates, by drawing lower temperature heat energy in the environment thermal source (as water, air), be converted to higher temperatures heat energy then and be released into and become high temperature heat source output in the circulatory mediator (as water, air).At this, owing to the running of compressor is done manual work and has been consumed electric energy, the running of compressor make different variable condition that the cold-producing medium of continuous circulation produces in different devices with different effects (i.e. evaporation heat absorption and condensation heat release) thus reached effect and the purpose that the recovery low-temperature heat source is produced high temperature heat source.The advantage of heat-pump water heater is: (1) conspicuous energy-saving effect; (2) can " peak load shifting ", the exploitation valley power consumption; (3) can realize that hot water, heating, cooling are integrated, improve efficiency of energy utilization; Utilization, the recovery of (4) be convenient to underground heat, building low-grade energies such as used heat.Further feasibility study shows that compare with other pot-type boilers, heat-pump water heater has higher economy, and its initial cost expection payback period is 2~3 years.With the ambient air is thermal source, and the heat pump assembly of placing the immersion coil pipe in the hot water storage tank can have a better effect.

Heat pump is draw heat from surrounding environment, and it is passed to heated object (object that temperature is higher), and its operation principle is identical with refrigeration machine, all according to contrary Carnot cycle work, different just operating temperature range is different.Wherein, the operation principle of heat pump is: as media, the refrigerants vaporize temperature is low with cold-producing medium for it, can vaporize at-40 ℃, so it and ambient temperature exist the temperature difference, refrigerant is vaporized after having absorbed extraneous temperature, heat by compressor compresses, become high temperature and high pressure gas, again behind heat exchanger and water heat-shift, through the expansion valve release pressure, get back to the liquefaction of low-temp low-pressure, the continuous circulation by cold-producing medium and with the water heat-shift, the water in the water pot is heated.A compression heat pump device, mainly containing evaporimeter, compressor, condenser and expansion valve four parts forms, by allowing working medium constantly finish the thermodynamic cycle process of evaporation (draw heat in environment) → compression → condensation (emitting heat) → throttling → evaporate again, thus with the transfer of heat in the environment in water.Heat pump is absorbed the energy QA that stores in the surrounding medium when work in evaporimeter; Itself consumes part energy, i.e. compressor power consumption QB; Carry out heat release QC by the working medium EGR in condenser, this shows, the energy of heat pump output is the heat QA that compressor work QB and heat pump absorb from environment; Therefore, adopt heat pump techniques can save a large amount of electric energy.

According to the thermal source difference, heat pump can be divided into air source heat pump, water resource heat pump and earth source heat pump etc.The air source heat pump technology is based on a kind of energy-saving and environmental protection of setting up against the Carnot cycle principle and heats technology.Heat pump apparatus of air source obtains low-temperature heat source by natural energy (air accumulation of heat), becomes high temperature heat source after the device efficient heat-collecting is integrated, and is used for getting (confession) warm or hot-water supply, and whole device collecting efficiency is very high.

At present, because heat pump techniques also is in developing stage on the whole, so it also has many technical being not enough to wait to improve.
