Pool Heat Pump -How does it work?
A pool heat pump is a special device that moves heat from one location to another with a small amount of energy. Pool heat pumps use less electricity because they use heat that is already available. INVERBOOST pool heat pumps are used for heating pools to transfer heat from the air into the water.
1 A unit of electrical energy (you pay for) runs the compressor which sucks evaporating Freon gas from the liquid-filled evaporator tube. This causes a strong cooling effect (just like sweat evaporates from your skin and cools you off). The gas picks up four units of heat from the air flowing over the outside of the evaporator tubes.
2 The compressor squeezes this gas, causing its temperature to climb above 200° F (93° C) Result: Five units of heat are added to the gas.
3 The hot, high-pressure gas flows through the inside of the condenser coil. The colder 80° F (26° C) pool water picks up the five units of heat from the Freon which cools it down back to a warm liquid.
4 The warm liquid is forced through a valve. As it drops in pressure, it rapidly expands and becomes an extremely cold liquid. This liquid flows back into the evaporator At 1 where it repeats the cycle.
Pool heat pumps are designed specifically for recreational water heating (in-ground, on-ground, or above-ground pools, spas, hot tubs, swim spas, etc.) If you have an air conditioner, dehumidifier, water cooler, or refrigerator, you already own a heat pump.
All these appliances use the same dependable technology to move heat from one place to another using electric power and a sealed refrigerant compression system.
Just like an air conditioner moves 2 to 3 units of heat from your home for every unit of electricity it consumes, heat pumps can use one unit of electric energy to move four (five or six for scroll models) units of heat from the air which delivers five to seven units of heat to your pool water.
INVERBOOST pool heat pumps usually use scroll compressors instead of the standard reciprocal compressors to achieve higher efficiency. It works efficiently on the outside temperature range -7℃~43℃. The cooler the outside, the less efficient they are and the higher energy bills they result. However, most people use them for outdoor pools during mild weather, this usually isn’t an issue.
Selecting a Pool heat pump
Usually, the price of a pool heat pump is more expensive than a gas pool heater. But the annual operating costs of a pool heat pump are typically lower than gas pool heaters because a pool heat pump has higher efficiencies. Pool heat pump lasts longer than gas pool heaters with proper maintenance. As a result, you’ll save more money in the long run.
When selecting a pool heat pump pool heater, you should consider its:
• Size
• Efficiency
There are many factors involving the size of the pool heat pump we chose. Basically, we choose a heater according to the surface area of the pool and the difference between the pool and the average air temperatures. Other factors also affect the heating load for outdoor pools, such as humidity levels, wind exposure, and cool night temperatures. Therefore, we recommend a larger heater.
The energy efficiency of a pool heat pump is measured by the coefficient of performance (COP). The higher the COP number, the more efficient.
