Product Overview

—— Product Description ——

Withair’s high temperature heat pump water heater, using the principle of the heat pump, draws heat from the ambient air through the thermodynamic cycle, then transfers the heat to the condenser through the compressor, and finally recurrently heats the water of the water tank to the required temperature. During the operation of the unit, there is no gas emission, it is environment-friendly and energy-saving. It can not only completely achieve water and electricity separation but eliminate the dangers like flammable, explosive, electric shock, poisoning, etc. that a traditional water heater may have. It adopts modular design, has flexible combination and strong expansion, and can heat all day long, the temperature of the water can be adjusted freely. Commercial hot water heater can be widely applied in the central heat supply of guesthouses, hotels, hospitals, schools, bathing centers and district and the factory hot water. The projects include a industrial hot water project, hotel hot water project, school hot water project, sauna hot water project and so on. Outlet hot water temperature can set from 55℃~80℃ as user requirement, so it is widely using home radiator heating by 65℃, 75℃, and 80℃ hot water for industry heating use --like a factory, textile, printing, and dying, military industry, steam line, ironing, explosive, medicine high-temperature sterilization line, oil drilling and so on. Suitable for high temperature hot water project and cold area heating project.

Withair high temp heat pump mainly uses electricity, but electricity is only used to drive heat pump system to absorb heat from outside environment. And then the heat is released to heat. Unlike conventional electric heaters, which directly use one-degree electricity to form 860 large calories, the experiment proves that the heat from the same one-degree electricity absorbed from outside for the heat pump system is four bits of 860 calories, so the electricity used is only 1/4 of the electric heater.

A simple analogy: a heat pump can use an electric energy to absorb 2-3 free heat from the environment, then use this heat energy for heating, and the electrical energy is also used for heating. The experiment will eventually make the heat efficiency up to 300-500% The general heating methods are directly heated by energy, the energy efficiency of the electric heater is 95%, and the natural gas is about 80%. The heat pump water heater uses electricity to drive the compressor, instead of being used directly for heating. The heat comes from the environment. Saving energy means saving money, it saves the operating cost of 3/4 compared with electric heating and oil furnace; saves 2/3 running cost compared with the gas heater; saves a large labor cost and environmental protection compared with coal. Even if compared with the solar energy, it can save the running cost of 1/3, and use the heat of valley electricity to shift the electricity from the peak periods to off-peak periods, so the run cost is saved again and again. The scope of application: high temperature heat pump water heater can meet the heating demand of agricultural and sideline products processing industry, beverage processing industry, electroplating dyeing industry, textile printing and dyeing industry, drying industry, disinfection, oil drilling and so on.
