What size air source heat pump do I need for my swimming pool?
Heat pump is the most effective tool to solve the problem of swimming
pool heating. A suitable air source swimming pool heat pump can save 65%-70% of
the cost of other heating equipment. In addition, the air source swimming pool
heat pump is a very environmentally friendly product, so it is favored by more
and more consumers and is becoming more and more popular in the market. So how
to choose the right air source pool heat pump for your swimming pool?
Here are the factors you should consider:
1. Energy efficiency ratio COP
COP is the ratio of heating capacity to electricity consumption. The
higher the COP, the higher the heating efficiency of the heat pump and the more
electricity saved. The COP of a heat pump is usually affected by the following
three conditions: air temperature, water temperature and humidity.
For example, a swimming pool heat pump with a COP of 8 means that it can
convert 1kW of electricity into 8kW of heat to heat the swimming pool under the
conditions of an air temperature of 15°C, a water temperature of 26°C, and a
humidity of 70%.
2. The size of the pool
We can choose the appropriate air source swimming pool heat pump model
according to the volume of heated pool water required.
The size of a swimming pool is usually measured in cubic meters (m3. For
a rectangular or square pool, 1000 liters = 1 cubic meter. For other curved
swimming pools, 1000 liters = 0.78 m3 (round swimming pool) = 0.89 m3
(elliptical swimming pool) = 0.85 m3 (bean-shaped swimming pool).
For example, for a circular swimming pool (length x width x height = 5m
x 5m x 2.5m), we should calculate the size of the pool as follows:
Length x width x height x 0.78 (Note: 0.78 is the radian value of the
circular pool).
Therefore, 5m x 5m x 2.5m x 0.78 = 48.75m3, or 48,750 liters.
3. Heating capacity
The heating capacity of the air source swimming pool heat pump is a key
factor. Generally 1kW can heat 6.5 to 7 cubic meters of swimming pool water
(under standard conditions).
Assuming that a swimming pool with a swimming pool cover is heated at
8-10 degrees Celsius, when the temperature is 26 degrees, each cubic meter of
water requires 0.4kW of heat; when the temperature is 15 degrees, each cubic
meter of water requires 0.3kW of heat to heat .
4. Use of swimming pool cover
If you are considering installing a heat pump for your own swimming
pool, it is recommended that you consider using a swimming pool cover. It is
very practical and can avoid the heat loss of the pool water (especially at
night) and reduce the heat loss by 50%.
If there is no swimming pool cover, you need to choose a heat pump with
stronger heating capacity (the heating capacity is about 35% stronger). For a
30m3 swimming pool with a swimming pool cover, a heat pump of 9.0-12.0kW can be
used. But if you have a swimming pool of the same size without a swimming pool
cover, you should choose 12.15-16.2kW air source swimming pool heat pump.
