"Calyenty" heat pumps utilize the sun's free heat by collecting and absorbing energy from the outside air. This energy is then compressed and transferred to the pool water. Your existing pool pump circulates the water through the heater and warms the pool. See the temperature chart.

The FAN circulates air through the outer EVAPORATOR AIR COIL that acts as a heat collector. The liquid refrigerant in the air coil absorbs the available heat in the ambient air transforming it into a gas. The refrigerant gas is then pumped into the COMPRESSOR. When this warmed gas is compressed, it intensifies or concentrates the heat like a magnifying glass in the sun.

This intensely hot gas is then pumped into the HEAT EXCHANGER CONDENSER where the actual heat transfer takes place. As the pool water passes through the heat exchanger, the hot gas gives up its heat to the cooler pool water.

The refrigerant returns to a liquid state and is pumped through the EXPANSION VALVE then into the evaporator air coil to start the process all over again.

To maximise the efficiency of your swimming pool heat pump, it should always be positioned outside, with at least 30 cm space around the unit, preferably in a sunny spot, although this is not essential

 






How does A Calyenty Heat Pump Work?

Heat Pumps are the most efficient generators of heat available today, and are used in many applications - from central heating in domestic houses to removing the heat from factories that need cooling to make conditions more comfortable for those present.

 

Swimming pool water is diverted to the pool heat pump by installing a bye-pass from the return pipe running from the pool filter to the return jets in the pool. This enables a simpler and cheaper installation, and utilizes the pool filter pump which usually runs for the right amount of time to enable consistent heating and achieve temperatures needed for comfortable swimming. Again it is better to run your pool filter pump during daylight hours i.e. when it is most likely that debris will enter the pool by traffic or wind, and also when the pool is most likely to be used by bathers.

Daylight hours are when the heat pump will run at its most efficient output, as this is when there is the greatest amount of ambient energy in the air.When the heat pump is running warm air is passed through the condenser effectively sucked through the vanes by the fan positioned in the top of the heat pump. The fan and the Hitachi, or Sanyo compressor are the only two components that consume any power. The heat pump extracts its energy from the ambient air which is now passing through the condenser, sometimes referred to as the evaporator coil.

The technology is similar to that utilized in refrigerators and air conditioning units. The compressor compresses refrigerant gas, R407C, which amplifies the heat absorbed from the air as it passes through the condenser. This heat is passed through a titanium double helix coil which is positioned inside the heat exchanger tank. The heat exchanger tank is made from PVC. The combination of the titanium coil and the PVC tank make the heat exchanger very resistant against corrosion due to the highly corrosive nature of swimming pool water, usually containing chlorine or salt. Any heat pump that does not use these critical materials in the heat exchanger will have a significantly reduced lifetime.

Calyenty heat pumps have a number of sensors and switches that help to operate the system to optimum efficiency and protect it against extreme external conditions.There is a state of the art digital controller with back lit screen, which is remote from the heat pump so that it can be installed somewhere convenient for the user. The main user controls for the heat pump are very simple, including the on/off switch and the temperature set buttons. Just set the desired temperature and leave it. The heat pump will only run when the temperature sensor senses that there is a need for the pool to have the temperature raised to the required level. This functionality can also be activated by our unique sms switch module. This enables the user to control his heat pump from anywhere in the world by just sending an sms message from his mobile phone.
