Section 3: HEAT PUMP OPERATION
3a: Quantum Heat Pump Pool /Floor/Water Heater
The heat pump pool heater developed by Quantum is an extremely efficient method of heating
a swimming pool, floor ,water or similar application. This new technology combines the direct
energy gain of an air-sourced evaporator with the constant heat acquirement of a high
performance heat pump.
The main components of the Quantum heat pump pool or floor heating system are: -
High efficiency heat exchanger (as hot side condenser)
Air sourced fin coil (as evaporator)
Thermostatic expansion valve
Efficient rotary compressor
The heat exchanger for pool heating is made with Titanium especially suitable for chlorinated
pool water.
The system uses the commonly available R22 or R407C or R417A refrigerant.
The 2.7kW Quantum pool heater is designed for domestic use but can also be used on smaller
commercial applications.
The Quantum heating system produces an operating sound of a similar type and level to the
outdoor unit of an air conditioner.
3b: Principle Of Operation
There is a flow switch installed which detects water flow through the heat exchanger. The
Digital Controller has a time delay at start, this time delay is set at 10 minutes. Once water
pressure has been detected, the Digital Controller will begin its time delay period. Heat pump
operation will commence after the time delay period has completed.
The time delay is also activated when any protection device restarts the system, including the
Digital Controller. The unit will be turned on or off by the Digital Controller, as part of normal
operation, in accordance with the water temperature and the set point of the Digital Controller.
When the Digital Controller, sensing a low water temperature, calls for the unit to restart, the
time delay will again be activated and the compressor will not begin operation until completion
of the time delay period.
Within 5 minutes of operation, the system will stabilise and it should be possible to observe a
temperature difference between the water inlet and outlet of approximately 4° C to 6° C,
depending on the ambient temperature.
