【 Weak current College 】 heat pump water heater Foundation--1

Central heat pump water heater is the gas water heaters, electric water heaters and solar water heater, hot water installation of a new generation is the alternative heating equipment for boilers. Heat pump water heaters to absorb the heat in the air and solar energy, is integrated heater and solar water heater safety advantages of energy-saving and environment-friendly water heater, 365 days a year, 24 x 7 operation, is the national of key promotional projects.

People are familiar with the "pump" is a way to increase the potential energy of mechanical equipment such as pumps the water main is improving or increasing the hydraulic pressure, the "heat pump" is a natural air, water or soil gets low heat, electrical work, output can be used for high-grade thermal equipment, is an energy-saving, environmental protection, clean heating and water heating equipment, heat pump technology in recent years attention in the world of new energy technologies.

First, how to understand the "heat pump"?

Take a simple example, the consumption of a few litres of gasoline car can turn a few tons of goods from one place to another place, the heat pump unit can absorb heat from the natural world through the heat pump's "handling" (electrical force-driven heat pump), access can be used for production, life energy.

Second, there are several heat pump?

According to sources of heat, heat pumps can be divided into air-source heat pumps, water source heat pump and geothermal heat pump.

3. heat pump water heater is solar products?

Broadly speaking, Yes, but the heat pump unit and conventional solar products has essential difference, mainly reflected in the different working principle: conventional solar products must rely on the direct rays of sunlight or radiation to reach the heating effect, and the heat pump unit mainly to absorb heat energy in the environment to achieve the heating effects.

4. heat pump units according to whatprinciples of production hot?

Heat pump equipment specifically reset an endothermic media – refrigerant, liquefied state below minus 20 degrees Celsius, and there is a difference in the outside temperature, the refrigerant can absorb the heat of the outside world, in the evaporator inside evaporation vaporization, heat pump unit of work in the compressor and refrigerant temperature, then through the condenser so that conversion from evaporating refrigerant for liquefied state status, transformation processes, releasing a large amount of heat that is transferred to the reserves of the water in the tank, the water temperature to achieve the purpose of the heater, which is the product of a unique, is the market potential of reason.

5. heat pump units with heat exchanger, the runtime must use electricity?

To use electricity, electric driven heat pumps only in from the outside environment to absorb heat and heat energy released heating hot water, unlike conventional electric water heaters, electric heating water directly, so power consumption is very small.

6. heat pump unit and other heating methods compared to what are the advantages?

Heat pump heating in: high efficiency, energy saving, environmental protection and safety. Non-combustible, explosive gases, no electrical drive components, absolutely safe; no waste gas, waste water, waste disposal, environmental protection, heat pump units annual average operating costs simply by direct heating of 1/4, fuel, gas heating with 1/3 ~ 1/2, 1/conventional solar 1.5.

7. initial investment and collection cycle?

Heat pump unit of initial investment than gas-fired boiler fuel, is slightly higher, but because of its special energy-saving effect, usually in less than a year and a half through energy-saving mode will cost recovery, boilers and other heating methods in general use life of only five years, and the heat pump service life up to 15 years.

8. air-source heat pump unit of electricity consumption in General?

Air-source heat pump unit for thermal efficiency typically 300%-500% to 40 ° c temperature rise, the production of one ton of hot water about power 9-15 degrees. And General Electric heating need power 52 degrees.

9. air-source heat pump hot water unit of use and simple operation?

Use is very simple, the entire units using automated intelligent control system, users need only open the initial use, the power supply in the use process completely automated operation, when the water temperature reaches a user-specified automatic stop, when the water temperature is lower than the user to specify their own power on the system, fully implement run 24 hours a day with hot water at any time without waiting.

Low temperature of 10 and in the winter, the heat pump unit is properly

Of course, air-source heat pump hot water unit with intelligent cream feature, ensure that the unit in low temperature environment and stable operation, it may, in accordance with the outdoor temperature, evaporator fin temperature and unit operating time and other parameters of the integrated, intelligent judge automatically enter and exit of tanks.

11, compared with conventional solar, air-source heat pump unit what are the advantages?

Advantages are obvious, primarily in four ways:

1. from the investment, such as to achieve the same effect of water supply, financing and heat pump hot water unit less than conventional solar products, and you can use economic power in electricity trough system hot water reserves.

2. from using aspects: General solar products affected significantly, wet weather, snow, night will not work, and heat pump hot water unit regardless of cloudy, rainy, snowy day, night or sunny can work as usual, provide hot water 24 hours a day.

3. from the operating costs of conventional solar energy in sunlight, almost zero-cost operation, unfortunately in the rain or snow or night can only rely on secondary system work, statistics show that in normal use, the conventional solar assisted system power consumption can heat pump chiller total power consumption can be high.

4. other functions: heat pump units used are not affected by the location restrictions, you can put it anywhere, and floor space is small, but conventional solar heating to achieve the same effect you will need to take up a large space, you must also put in the open; heat pump hot water in the system at the same time can produce air conditioners for dehumidification, cooling and air filters, and other accessibility features.
