CHROMAGEN SWIMMING POOL HEAT  PUMP.

Features

Environmentally-friendly pool heating & cooling:

Heating & Cooling Modes:

  • The Midea heat pump water heater features heating and cooling modes making it a versatile system for maintaining the perfect water temperature all over Australia including locations such as Cairns and Darwin
  • In heating mode the Midea heat pump water heater has a Coefficient Of Performance (COP) of 4-6* and a COP of 3.5* in cooling mode. (*Depending on geographic location)
    The Midea heat pump works effectively even at low ambient temperatures such as -
    - Heating Mode Working Range: -7C~38C
    - Cooling Mode Working Range: 15C~43C
  • Midea utilises only ozone-friendly R410a refrigerant to minimise pollution and depletion of the Ozone layer

Long service life:

Titanium heat exchanger with Hydrophilic fin coil coating:

  • Provides high corrosion-resistance against aggressive pool water

Temperature management & convenience:

Advanced User Interface & optional remote wire controller

  • With a Midea Heat Pump, set up and operation monitoring is made simple thanks to an amazing, user-friendly touch pad interface with clear Liquid Crystal Display
  • Features include temperature and time setting, pool pump activation and fault alarm
  • Midea heat pumps also include a remote wire controller with 15 metre lead, for convenient operation from your house or alternative location

Safety:

Automatic defrosting function

  • Allows system to warm up prior to normal operation to de-ice and therefore protect vital components whilst also ensuring highest operational efficiency

Self-protect function

  • The compressor features a self-protect function

  • Typical incoming cold temp for each city used (Adelaide = 17C / Brisbane = 20.5C / Canberra = 15C / Hobart = 13C / Melbourne = 14.5C / Perth = 18C / Sydney = 17.6C)
  • Final pool temp = 27C; Final spa temperature = 38C
  • 1 x 14kW unit. (Using 2 x 14kW units will reduce the heat up time by approximately 50%)
  • Pool/spa covered during heat up period

How it works


Heat pumps are designed to transfer heat from one medium to another using only a small amount of power.

  1. A fan draws in air, containing heat energy, across the evaporator
  2. The cold liquid refrigerant in the evaporator absorbs the heat energy from the air and turns into a warm gas.
  3. The compressor pressurises the refrigerant and turns it into a super-hot gas
  4. The super-hot gas moves into the condenser where the heat is transferred to the circulating pool water via a heat exchanger
  5. The refrigerant reverts back to a liquid after and continues back to the evaporator as a cold gas for the process to start again

A heat pump pool heater is like an energy multiplier. From 1 kW of power consumed, it can create up to 5 kW of water heating energy. That's a performance efficiency of a remarkable 500%. Heat pumps are more energy efficient than gas pool heaters, where their output performance efficiency may only be around 80% of energy input.

The table below demonstrates how the efficiency of a heat pump pool heater transfers to a lower running cost for heating a 50,000 pool in Sydney.

HP pool heating 30c 500% 6c / kWh $366
 *Based on the following conditions: 27C pool temperature. Excludes circulation pump energy requirements

So where does the FREE energy come from? The AIR!
The air around us contains latent energy which can be harvested using common refrigeration technology. Refrigerant technology utilises refrigerant gas; an amazing substance that boils at low temperatures and can therefore transition easily from a liquid to a vapour.

The heat pump cycle simply takes the refrigerant through various states in a process of super-heating and cooling, where the heat energy is imparted on the pool water using a heat exchanger.
