Air-source heat pump is one of the most advanced energy, air-source heat pump working principle is different from solar and ground source heat pump, air-source heat pump and solar, ground energy are free energy, is the product of the development of advanced energy-saving technology, air-source heat pumps can be used for domestic hot water, air conditioning, home heating, and many other areas, has become a symbol of high technology and high quality of life, the following to come together! Recognize the principle of air source heat pump.
Air-source heat pump principle
Air-source heat pump principle is the use of inverse Carnot principle, with very little electricity, absorbing a large amount of low-temperature heat in the air, through the compressor's compression into high-temperature heat, is a kind of energy-saving and efficient heat pump technology. Air source heat pump in operation, the evaporator from the air in the environmental heat energy to absorb heat to evaporate the heat transfer mass, mass vapor compressed by the compressor pressure and temperature rise, high-temperature vapors through the permanently bonded to the outside surface of the storage tank of the special annular tube condenser condensation into liquid, the heat released to the air source heat pump storage tank of water, the heat transfer mass after condensation through the expansion valve back to the evaporator, and then be evaporated again, and so on. And then be evaporated, and so on.
Two, air-source heat pump energy-saving principle
The following figure can help understand the inevitability of air-source heat pump energy saving, because the absorption of heat from the outdoor air is free of charge, and heat production is dominated by it. Air source heat pump heat balance formula is:Heat supply = heat absorbed from outdoor air + consumed electricity
Cooling supply = cold absorbed from outdoor air + consumed electricity
For example: a person picks up a stretcher from the development zone to the city with a maximum of 100 kilograms. How much work he does and how much force he uses has a measurable quantitative and constant value. The same with so much force to do how much work to push a car, with the help of the car this equipment, can be 400 kilograms of goods with the same so much work, the same so much force, pushed to the city. So with the help of such equipment as a car, the effect is four times greater than the effect of the pick and carry. So the heat pump this kind of equipment is similar to the car, and ordinary electric, gas, coal-fired hot water equipment is similar to a person picking a stretcher.
Heat pump products belong to the solar energy products?
From the working principle, does not belong to the conventional solar energy products. Heat pump products and conventional solar products are more different, conventional solar products using water as a medium, you must rely on direct sunlight or radiation to achieve the heating effect, and products, the use of refrigerants to absorb heat energy in the air and solar radiation energy, and through the compressor compression of the heat with the water after the exchange of heat to achieve the effect of heat, so the products and air conditioning principle is the same.?
What is the working principle of heat pump products?
Products use refrigerant as a medium, refrigerant vaporization temperature is low, at -40 ℃ can be vaporized, therefore, it exists with the outside temperature temperature temperature difference, the refrigerant absorbs the outside temperature vaporization, through the compressor compression of the heat, into a high-temperature, high-pressure gas, and then through the heat exchanger and the exchange of heat with the water, through the expansion valve to release the pressure back to the low-temperature, low-pressure liquefied state through the refrigerant cycle and exchange of heat with the water, will be the same principle as air conditioning. and exchanging heat with water, heating the water in the tank.
Do heat pump products require electricity?
Must use electricity, the compressor uses electricity to compress the heat, not direct heating, air-source heat pumps also have fans, which also need electricity, but use less electricity.?
Why are heat pump products characterized?
?1, not affected by the environment, available all year round;?
?2, outstanding energy efficiency, short payback period;?
?3, environmentally friendly products, without any pollution;?
?4, long service life, low operating costs;?
?5, safe operation, unmanned operation;?
?6, modular design, easy to install.?
? What are the advantages of heat pumps over conventional solar products?
?1, wide range of application, the product applies to the temperature range of -10-40 ℃, and year-round all-weather use, not subject to cloudy, rain, snow and other inclement weather and the impact of the winter night, can be used normally.?
2, can be continuously heated, compared with the traditional solar water storage type, heat pump products can be continuously heated, continuous hot water, to meet user demand.
3, low operating costs: compared with conventional solar energy, in the spring, summer and fall when the sun is better, the operating costs are higher than solar energy, but in the cloudy and rainy days and nights, the thermal efficiency is much higher than the solar energy of the electricity-assisted heating. On average throughout the year, conventional solar assisted systems consume much more energy than the total annual energy consumption of the product throughout the year.?
4, easy to install: air-source heat pump occupies very little space, the shape is similar to the air conditioning outdoor unit, can be directly connected to the insulation tank or connected to the heating pipe network, suitable for large and medium-sized cities, high-rise buildings, for large-scale centralized heating problems, the product is the best choice.?
What are the advantages of heat pump products compared with boilers?
1, high thermal efficiency: the product thermal efficiency year-round average of more than 300%, while the boiler thermal efficiency will not exceed 100%.?
2, low operating costs: with oil, gas boilers than the average annual energy savings of 70%, coupled with the low price of electricity and rising fuel prices, the advantages of low operating costs are increasingly prominent.
3, environmental protection: heat pump products without any combustion emissions, refrigerant selection of environmentally friendly refrigerant R417A, zero pollution of the ozone layer, is a better environmentally friendly products.
4, safe operation, no need to guard: compared with the fuel boiler, the operation is absolutely safe, and fully automatic control, no need for personnel guard, can save personnel costs.
5, modular installation, easy to add equipment: the product adopts the installation mode of multiple units in parallel, when the user's water consumption increases, you can add equipment at any time.
What are the disadvantages of heat pump products compared with boilers?
1, slow heating: heat pump products are refrigerant as a medium, using the compressor compression heating mode, compared with the direct heating mode of the boiler, the speed is relatively slow.
2, a one-time investment: with oil, gas boilers than when the water consumption is greater than 10 tons, a one-time investment is greater than the boiler, the greater the water consumption, the greater the relative investment in the product.
3, heating water temperature is limited: heat pump water temperature is generally 60 ℃ (water-source heat pump up to 80 ℃), can not produce more than 80 ℃ high temperature water or steam.
