What are the advantages of air energy heat pump in hotels?

As a typical representative of energy saving and environmental protection, air source heat pump has unique characteristics. Compared with other energy sources, it has many advantages such as energy saving and environmental protection, and does not occupy indoor area. Central air conditioning heating system suitable for large buildings. But things are not perfect, and the air source heat pump also has some shortcomings, as follows:

Advantages:

1, with wide application range. The applicable temperature range is -7 to 40℃, which can be used all year round, and is not affected by bad weather such as cloudy days, rain and snow, winter nights, etc., and can be used normally. It can be heated continuously. Compared with the traditional solar water storage type, heat pump products can continuously supply heat and water, which meets the needs of users. It is suitable for all kinds of groups in hot water engineering, and can realize unattended and fully automatic operation. Centralized hot water supply, with water temperature and water level display.

2. Low operating cost. Outstanding energy-saving effect, short payback period, air source heat pump can save energy by 70%; Compared with the solar water heater assisted by gas, electricity and electricity, the annual cost is the lowest, about 1/3 for gas water heater and 1/4 for electric water heater. Short-term recoverable investment. Every power consumption 1kw can generate an average of 4kw of heat energy, which is about 3 times more than that of electric hot water boiler.

3. Environmental protection products. No pollution, no combustion emission, no harm to human body and good social benefits.

4, stable performance, not affected by the environment. Products run all the year round, not affected by bad weather such as night, cloudy day, rain and snow. It can make hot water 24 hours a day, 365 days a year.

5, convenient. The air energy heat pump occupies a small space, and its shape is similar to that of an outdoor unit of an air conditioner. It can be directly connected to the heat preservation water tank or heating pipe network, which is suitable for high-rise buildings in large and medium-sized cities and is the best choice for large-scale central heating. There is no need for solar collectors, which reduces the floor space by 95%. When used together with solar hot water equipment, it can reduce the floor space of solar collectors by 50%, save a lot of floor space of solar collectors and reduce the volume of hot water storage tank.

Disadvantages:

1, which is inefficient and limited by the region. Because air energy is a dispersed energy source, the heating speed is slow and the thermal efficiency is not very high. In addition, air-source heat pumps are prone to frost, and due to geographical restrictions, air-source heat pumps are more suitable for use in Central and South China.

2. The compressor burns out easily. At present, circulating heating system is widely used in air energy water heaters on the market, which easily leads to aging and carbonization of compressors under high temperature and high pressure. If the lubrication effect of the system is not good, it is easy to cause the compressor to be burned out.

Generally speaking, air source heat pump has many advantages and few disadvantages, which is why air source heat pump technology is so sought after now. Air source heat pump technology is not only widely used in the field of water heaters, but also has good performance in the field of air conditioning and heating, and the application field of air source heat pump will be broader.
