What is the difference between air source heat pump water heater and solar energy?
Does the heat pump water heater need electricity when running?Answer: yes. Heat pump water heater needs to consume a small amount of electrical energy, so that the machine work to absorb the heat in the outside environment, and release hot water, but not like conventional electric water heaters that use electricity directly heating water, so the electricity consumption is very little. Its efficiency is not governed by the efficiency of energy conversion (100% is the limit).
Is the heat pump water heater solar energy product? What's the difference between it and solar water heater?Answer: in broad sense, heat pump water heaters belong to solar energy products, from the principle of work, does not belong to the traditional solar products. It is essentially different with the conventional solar water heaters, mainly reflected in the different working principle: conventional solar water heater must rely on exposure to direct sunlight or heat radiation system to achieve results, and if the party according to the principle of Kano heat pump heating, the refrigerant absorbs heat energy and solar radiation in the air and through the compressor compression heating heat exchange with water to achieve the heating effect.
What is the principle of heat pump heating?Answer: heat pump equipment dedicated to a heat absorbing medium - refrigerant, its evaporation temperature is less than 20 below zero. C and the outside temperature exists temperature difference, therefore, can absorb the heat of the refrigerant in the evaporator, the internal evaporation, improve the temperature of refrigerant through the compressor heat pump equipment in the work, and then through the refrigerant from the condenser into vapor state for liquefied state, in the process of transformation, release a lot of heat transfer to the water in the water storage, the water temperature increased, reaching the purpose of producing hot water.
What is a heat pump? How many kinds of heat pumps are there?Answer: heat pump is a kind of energy from the nature of the air, water or soil to obtain low grade heat, high grade heat equipment after the output power of power can be used, in accordance with the different heat sources are generally divided into the air source heat pump, water source heat pump and ground source heat pump three. The name of the heat pump vividly illustrates its principle that it is a pump, which carries not water, gas, oil, but heat". It is not a heat transfer device, but a heat transfer equipment, so its efficiency is not subject to the time conversion efficiency (100% is the limit).
