Low temperature air source heat pump working principle
1. The working principle of low temperature air source heat pump
Air source heat pump units by the evaporator, condenser, compressor and expansion valve four main parts form a closed system, which filled with the right amount of working medium.Unit operation principle is based on inverse circulation principle: liquid working substance in the first place in the evaporator absorbs heat from the air and steam evaporation formed (evaporation), latent heat of vaporization is reclaimed by heat, and then by the compressor compressed into high temperature and high pressure gas, into the condenser condensed liquid (liquid) need to absorb heat heating water, liquid working substance after decompressional expansion of the expansion valve back on expansion valve, absorbing heat evaporation and complete a cycle, so on, constantly absorbing the low temperature water source of heat and heat output, directly to the expected temperature.
2. The characteristics of low temperature air source heat pump
Because it is not used directly heated by electric heating element, the relative electric heat pump water heater, to eliminate the leakage of the security hidden danger;Relative gas water heater, no gas leak, or safety concerns, such as carbon monoxide poisoning, thus has more excellent safety performance.
Air source heat pump is regenerative, function according to the temperature of the tank heating or air conditioning load start automatically, to ensure adequate supply 24 hours hot water, air-conditioning loads, heating hot water won't appear like a gas water heater can't satisfy the multiple problems with hot water faucet, at the same time also won't appear electric water heater capacity is small, many people take a shower to wait.Out-of-the-box hot water, large water yield, water temperature stability, meet all your expectations of hot water.
Due to the power consumption of other heating, heating and living hot water costs a quarter, which is equivalent to using the same amount of hot water or the same heating area, use the air to heat pump, only a quarter of the electric heating, heating bills.
D. Green environmental protection
Water heater burning gas by burning combustible gas heating hot water, large amounts of carbon dioxide emissions at the same time, the harmful gas such as sulfur dioxide.Air source heat pump is only transfers heat from the surrounding air to the water, fully achieve zero emissions, almost does not affect to the environment, is the real environmental protection water heater.
E. Low carbon fashion
In today's energy conservation and emissions reduction has become the trend of The Times, save energy and reduce carbon emissions is one of the most fashionable way of life.As mentioned earlier, air source heat pump is the reverse carnot principle, the energy is transferred to the water in the air, not directly use electric heating element to heat, so its energy efficiency can be up to 4 times of electric water heater, that is the same amount of hot water heating, power consumption is equivalent to a quarter of the electric water heater, greatly saves the consumption of electricity.
