Attachment: heat pump knowledge question and answer

The familiar "pump" is a kind of mechanical equipment that can improve potential energy. For example, a water pump is mainly used to raise the water level or water pressure, and a "heat pump" is a kind of equipment that can obtain low-grade heat from air, water or soil in nature and output high-grade heat for people to use through electric work. It is an energy-saving, environment-friendly and clean heating and hot water equipment. Heat pump technology is a new energy technology that has attracted worldwide attention in recent years.

First, how to understand "heat pump"?

For a simple example, a car can transport several tons of goods from one place to another with several liters of gasoline. Heat pump units can absorb heat from nature, and get heat energy that can be used for production and life through the "handling" of heat pumps (electric power does work to drive heat pumps).

Second, how many kinds of heat pumps are there?

According to different heat sources, heat pumps can be divided into air source heat pumps, water source heat pumps and ground source heat pumps.

3. Is the heat pump water heater a solar product?

Broadly speaking, yes, but there are essential differences between heat pump units and conventional solar products, mainly reflected in the different working principles: conventional solar products must rely on direct sunlight or radiation to achieve heating effect, while heat pump units mainly absorb heat energy in the environment to achieve heating effect.

4. According to what principle does the heat pump unit collect heat?

The heat pump unit is equipped with heat-absorbing medium-refrigerant, which is lower than MINUS 40.5℃ in liquid state and has a temperature difference with the outside temperature. Therefore, the refrigerant can absorb external heat energy, evaporate and vaporize in the evaporator, increase the temperature of the refrigerant through the operation of the compressor in the heat pump unit, and then convert the refrigerant from the vaporized state to the liquefied state through the condenser. During the conversion process, a large amount of heat is released and transferred to the reserve water in the water tank, thus increasing the water temperature.

5. There is a heat exchanger in the heat pump unit. Is it necessary to use electricity during operation?

Electricity is needed, but electricity is only used to drive the heat pump to absorb heat from the external environment and release heat energy to heat hot water, instead of directly heating water like conventional electric water heaters, so the electricity consumption is very small.

6. What are the advantages of heat pump units compared with other heating methods?

The heat supply of heat pump unit is mainly reflected in: high efficiency, energy saving, environmental protection and safety. No flammable and explosive gas, no electric drive components, absolutely safe; No waste gas, waste water and waste residue are discharged, which is absolutely environmentally friendly. The average annual operating cost of heat pump unit is only 1/4 for direct electric heating and 1/3~ 1/2 for oil-gas heating.

7. What is the initial investment and payback period?

The initial investment of heat pump unit will be slightly higher than that of oil-fired and gas-fired boilers, but due to its special energy-saving effect, the cost can be recovered by energy-saving methods within one and a half years. The service life of boilers and other heating methods is generally only five years, while the service life of heat pump units can be as long as fifteen years.

8. What is the power consumption of air energy heat pump unit?

Generally, the thermal efficiency of air energy heat pump unit is 330%-500%. Based on the temperature rise of 40℃, it takes about 9- 12 degrees to produce one ton of hot water. Ordinary electric heating method needs to consume 52 kwh of electricity.

9. Is the use and operation of air energy heat pump water heater simple?

It is very simple to use. The whole unit adopts automatic intelligent control system. Users only need to turn on the power for the first time, and fully realize automatic operation in the later use process. When it reaches the water temperature specified by the user, it will automatically stop; when it is lower than the water temperature specified by the user, the system will automatically start to run, completely realizing 24-hour hot water at any time without waiting.

X can the heat pump unit operate normally when the temperature is low in winter?

Of course, the air energy heat pump hot water unit has intelligent defrosting function, which ensures the stable operation of the unit in low temperature environment. It can automatically enter and exit the box according to the comprehensive intelligent judgment of outdoor environment temperature, evaporator fin temperature and unit running time.

XI。 Compared with conventional solar energy, what are the advantages of air energy heat pump unit?

The advantages are very obvious, mainly reflected in four aspects:

1. In terms of investment: if the same water supply effect is achieved, the investment of heat pump hot water unit is less than that of conventional solar products, so it can use economical electric energy as hot water reserve with low power consumption.

2. In terms of use, conventional solar products are obviously affected by the weather, so they can't work in rainy days, snowy days and nights, while heat pump hot water units can work as usual in cloudy days, rainy days, snowy days, nights or sunny days, providing hot water all day.

3. From the operating cost, the conventional solar energy runs almost at zero cost under direct sunlight, but it is a pity that it can only rely on auxiliary systems in rainy and snowy days or at night. Statistics show that under the same water supply, the annual power consumption of conventional solar auxiliary system is basically the same as that of heat pump unit.

4. Other functions: the use of heat pump unit is not limited by location, and it can be placed anywhere, occupying a small space, while conventional solar energy needs to occupy a lot of space and must be placed in the open air to achieve the same heating effect; Heat pump unit can produce cold air while making hot water, which is used for dehumidification, refrigeration, air filtration and other auxiliary functions.

12. Is it necessary to provide a computer room?

No, the heat pump unit can be placed anywhere you specify, without affecting the beauty of the building, with small space and no direct light. The installation is very easy, and it can be placed in the open air, or in an inconspicuous corner or basement, and it can realize unmanned operation and automatic control of constant temperature water supply.

XIII. Where can heat pump units be used?

Heat pump units are widely used, including all kinds of commercial machines specially designed for hotels, hotels, schools, hospitals, saunas, beauty salons, swimming pools, laundry rooms, industrial and mining, and all kinds of household machines specially designed for families. At the same time, air conditioning can be obtained free of charge, which can realize year-round heating.

14. If multiple heat pumps are used, will the failure of one of them affect the whole system?

Does not affect. The air energy heat pump unit has modular function and is connected to the power grid. Each heat pump unit can be controlled independently. Even if one of them has a problem, it will not affect the normal operation of other units during maintenance.

15. Is the heat pump unit running stably?

The operation is very stable and reliable. The air energy heat pump is specially equipped with high and low pressure protection, anti-freezing protection in winter, over-high exhaust temperature protection, over-high outlet temperature protection, insufficient water flow temperature difference protection, water flow switch protection and compressor operation and shutdown delay protection.

What are the advantages of heat pump products compared with oil-fired boilers?

1, high thermal efficiency: the annual average thermal efficiency of products is about 380%, while the thermal efficiency of boilers will not exceed 100%.

2. Low operating cost: Compared with oil-fired and gas-fired boilers, the average annual energy consumption can be reduced by 70%, and the advantage of low operating cost is increasingly prominent due to the reduction of electricity price and the increase of fuel price.

3. Environmental protection: the heat pump product has no combustion emission, and the refrigerant is environmental protection refrigerant R4 17A, which has no pollution to the ozone layer and is a good environmental protection product.

4. Safe operation without duty: Compared with oil-fired boilers, it is absolutely safe to operate without full control on duty, which can save personnel costs.

Modular installation, easy to add equipment: the product is installed in parallel with multiple units, and equipment can be added at any time when the user's water consumption increases.
