Total Energy Heat Pump

A Total Energy Heat Pump is a combination of Air Source Heat Pump and Water Source Heat Pump, it serve as a normal air cooled chiller unit and hot water heat pump as well. Total Energy Heat Pump is capable to produce chilled water and hot water to meet both the cooling and heating demand simultaneously for the air-conditioning system and hot water system.

The Total Energy Heat Pump is designed to cool chilled water from 12.5 degree C to 7 degree C and to heat hot water up to 65 degree C simultaneously, it consist of compressors, air heat exchanger (condenser coil), two nos. of water-side heat exchangers for chilled water and hot water respectively, necessary numbers of electronic expansion valves and intelligent electronic refrigerant flow control and all necessary accessories.

There are five operating modes to cater for the demand and priority on cooling and heating loads:

  1. Heating Mode - An air source heat pump to produce hot water when there is no cooling requirement.
  2. Heat recovery Mode - A water to water heat pump to provide chilled water as well as uncontrolled hot water simultaneously.
  3. Cooling Mode - An air-cooled package chiller when there is no heating requirement.
  4. High Cooling and Small Heating Mode - The energy absorbed from chilled water side is partially recovered by the heat exchanger and transfer to hot water side, the surplus heat energy is rejected to the outdoor via the condenser at the same time.
  5. Small Cooling and High Heating Mode - The energy absorbed from chilled water side is fully recovered by the heat exchanger and transfer to hot water side, and at the same time the air heat exchanger absorbs heat energy from outdoor air to provide extra heat energy to meet the total heat load.

 

Features:

  • Heating capacity 6 kW to 250 kW with scroll compressors.
  • Heating capacity 80 kW to 600 kW with screw compressors.
  • Refrigerant R134a (or R407C).
  • Hot water temperature at 65C to kill Legionnaires.
  • Double wall heat exchanger to avoid contamination.
  • Low noise with 65dBA @ 2 meters
  • Reverse cycle defrost system, operation at outdoor -10C.

Total Energy Heat Pumps can be used in many more applications including large commercial projects, swimming pools, sports facilities, hotels, club houses, SPA, health care facilities, schools, apartments and food industry.
