Abstract
The invention relates to a solar energy hot water device which is assisted through an air source heat pump, and the solar energy hot water device comprises a heat collector, a hot water tank, a supporting rack, and an auxiliary heating device of a solar water heater. The invention is characterized in that the auxiliary heating device of the solar water heater is the air source heat pump. When the natural circulation type air source heat pump device of the invention is adopted to replace an electrical heating tube to be used as the auxiliary heating equipment of the solar water heater, under the circumstance of the same condition of the hot water output, the required electrical energy is only about one fourth, and the security is ensured when in use.
Description
Technical field
The invention belongs to apparatus for heating water by solar energy with the auxiliary heating of air source heat pump.
Background technology
Solar energy is inexhaustible, nexhaustible clean environmental protection regenerative resource.Solar water heater, and will more enter huge numbers of families.For guaranteeing that solar water heater also can be the round-the-clock hot-water supply of user in the sunlight deficiency, present a considerable amount of solar water heater all adopts electric energy as supplementary energy, and electrothermal tube promptly is installed in solar water heater water tank, and (power is generally 1.5～2.0kw).Is power consumption big (the electrothermal tube thermal efficiency about 95%) with electrothermal tube as the shortcoming one of assisting firing equipment, the 2nd, because of electrothermal tube directly contacts with water, might produce problems such as electric leakage, electric shock, and there is potential safety hazard.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of little power consumption, safe in utilization substitutes conventional electrothermal tube as the auxiliary heating of solar water heater facility with heat pump apparatus of air source.
The present invention solves the problems of the technologies described above with following technical scheme:
Apparatus for heating water by solar energy with the auxiliary heating of air source heat pump has heat collector, boiler, support and auxiliary heating of solar water heater device, it is characterized in that the auxiliary heating of solar water heater device is a heat pump apparatus of air source.
When adopting natural recirculating type heat pump apparatus of air source of the present invention to substitute conventional electrothermal tube as the auxiliary heating of solar water heater device, under the identical situation of heat outputting water condition, required electric energy only is about 1/4 of an electric heating; Because its heating process water power is isolated fully, guaranteed the safety of using again.
Description of drawings
Fig. 1 is the structural representation of the present invention with the apparatus for heating water by solar energy of the auxiliary heating of air source heat pump.
Fig. 2 is the right view of Fig. 1.
Fig. 3 is a kind of structural representation of heat pump apparatus of air source.
The specific embodiment
Use the apparatus for heating water by solar energy of heat pump apparatus of air source 4 as the heating servicing unit, heat collector 1 is the main hot equipment of adopting, what be connected with boiler 2 has a heat pump apparatus of air source 4, the running water inlet of boiler 2 (the hot water circuit mouth of holding concurrently) 5 connects the upper circular tube 10 of heat pump apparatus of air source 4, and the hot water outlet of boiler (circulation port down of holding concurrently) 6 connects the following circulation pipe 11 of heat pump apparatus of air source; Also be provided with exhaust outlet (the observing and controlling sensor import of holding concurrently) 7, sensor 8 on the boiler.This device also has a control panel measurement and control instrument, picks out measurement and control instrument power line, sensor signal lines and heat pump power line by measurement and control instrument.The position of the electrothermal tube of the solar water heater that electrothermal tube 9 shown in dotted lines in Figure 2 is former conventional design.
In practice, as long as the electrothermal tube power line of the solar water heater of former conventional design is changed into the power line of heat pump apparatus of air source.Heat pump apparatus of air source is by the time and the temperature control start and stop of measurement and control instrument.During startup, measurement and control instrument is connected the heat pump compressor power supply automatically and is worked and (establish electric energy and be input as Q
1), making evaporator operation, the working medium in the evaporimeter has absorbed the energy Q in the air source
2After, again energy Q
1+ Q
2Take in the condenser in the heat-exchanging water tank and the water positive energy exchange, thereby add hot water.Water temperature raises in the water tank, and density diminishes, and water moves toward the top, and then enters the top of solar energy hot water tank 2 from upper circular tube 10; The water of boiler bottom is then because density is bigger, arrive the bottom inlet of heat-exchanging water tanks from following circulation port 6 through circulation pipe 11 down, so constantly circulation is heated to temperature required (general≤60 ℃) to the boiler whole box water, controller cuts off compressor power automatically, quits work.If the gross energy that hot water obtains is Q
3
In the whole process that adds hot water, if when disregarding loss, energy-balance equation is:
Q
3(energy that hot water obtains)=Q
1(electric energy that heat pump compressor consumes)+Q
2(heat energy that obtains from the air source).
Below be to two kinds of usefulness examining reports with the apparatus for heating water by solar energy of the auxiliary heating of air source heat pump of the present invention: 1. model 1P (950W), compressor Panasonic produces, water tank volume 100L
