Advantages and disadvantages of air source heat pump heating

The advantages of air source heat pump heating are: comfort, energy saving, convenient terminal selection, long service life, good safety performance, low operating cost and stable performance; Disadvantages are: the efficiency of low temperature environment is reduced, and the main engine of air energy heat pump is relatively large. If the power outage is long in winter and the drainage is not timely, the pipeline may freeze and the machine may be damaged.

First, advantages:

1, comfortable and energy-saving.

The heating heat of the air energy heat pump floor heating rises from the feet, so that the temperature distribution in the whole indoor space is uniform and there is no hot air feeling, which is beneficial to the body to keep moisture and has a positive therapeutic effect on rheumatism and asthma. Air energy heat pump floor heating can produce hot water at 35-60℃, and the heat is concentrated at the benefit height of human body (below 2 meters), which saves 75% energy compared with traditional electric heating.

2, terminal selection is convenient and the service life is long.

There are many options for indoor cooling terminals, such as floor heating coil, radiator and fan coil. Long service life, low maintenance cost and service life exceeding 15 years.

3. Good safety performance and low operating cost.

Different from electric and gas water heaters, it uses indirect heating to exchange heat with water, and there are no potential safety hazards such as electric leakage and air leakage. The payback period of investment is short, and the air source heat pump can save energy by 70%.

Compared with gas-fired, electricity-fired and electricity-assisted boilers, the annual cost is the lowest, about 1/3 of gas-fired boilers and 1/4 of electric boilers. 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.

4. Stable performance.

Not affected by the environment, the product runs all the year round, and is not affected by bad weather such as night, cloudy day, rain and snow. It can provide hot water 24 hours a day, 365 days a year.

Second, the shortcomings:

1, the main engine of air energy heat pump is relatively large, and the efficiency of low temperature environment is reduced.

The main engine of air energy heat pump is relatively large in shape and needs to be installed on ventilated ground or roof, so it has higher requirements on the environment. In low temperature environment, the heat capacity of air energy heat pump floor heating mechanism will decrease with the decrease of ambient temperature.

2. If the power is cut off for a long time in winter and the water is not drained in time, the pipeline may freeze and damage the machine.

Whether it is air energy heat pump heating or air energy heat pump making domestic hot water, today's air energy has penetrated into two major areas of life, leading the hot water supply trend and new heating direction in the new era. The reason is, on the one hand, the general trend of new energy popularization, on the other hand, the powerful function of air energy heat pump heating impressed users.
