How Does your Kopec Heat Pump heat your
pool?
A heat pump uses a refrigerant technology
to gather heat in the outside air and transfers it to your pool water.
This technology is used because refrigerant can absorb and transfer
heat.
The circulating fan pulls air trough the evaporator coil which acts
as a heat collector. The very cold liquid refrigerant in the evaporator
absorbs the warmth from the outside air, which in turn changes the state
of the refrigerant from a liquid to a gas. The refrigerant gas is then
pumped into the compressor where it is compressed and increases to a
very high temperature.
This extremely hot gas then flows into the heat exchanger, where the
heat transfer begins. As the cool pool water flows through the heat
exchanger, the hot gas gives up its heat, which increases the water
temperature. Once the refrigerant gives up its heat, it returns to a
liquid state, then passes through an expansion valve and into the evaporator
coil to start the process all over again.
Performance Effective
Factors
It is very important to understand that
heat pump pool heaters are designed to maintain temperature and do not
heat quickly. Initial heat up time could be as much as 24-48 hours,
because it is necessary to heat the concrete walls in the pool, as well
as the water. Once your desired temperature is reached, the heat pump
will maintain that temperature, providing the circulating pump run time
is adequate, depending on temperature desired, size of pool and outside
weather conditions. Listed below are a few factors to consider when
evaluating your unit's performance.
Size of your pool: Most of your
heat loss is through the surface area of the pool. The larger the pool,
the quicker it will loose temperature.
Wind: Since surface area is the
biggest cause of heat loss, the more wind you have across your pool
increases your heat loss even more. Normal wind speed is 2-3 mph.
Water Temperature Maintained:
If you want a higher temperature, you'll have to run the unit longer to
maintain it. The greater the difference between air temperature and
water temperature means more heat loss and longer run time requirement.
Waterfalls, Spillways and Fountains:
These features increase heat loss. Shut off features cut down heat loss
and improve heater's performance
