AIR SOURCE HEAT PUMP

• Moderate cost
• Controlled output temperature normally up to 64C
• Can operate at mains water pressure

5
HOW DOES A HEAT PUMP WORK

• A heat pump water heater uses the same technology
  and mechanical principles as refrigerators and
  air conditioners
• HPWHs take heat from the surrounding air or other
  heat source and uses it to heat low pressure
  liquid refrigerant in the heat pumps evaporator
• The refrigerant then passes through the
  compressor which raises the refrigerant pressure
  and the temperature
• The heated refrigerant gas passes through the
  heat pump condenser where it gives off its heat
  the water and condenses back into the liquid
  state
• The refrigerant now passes through an expansion
  valve where the pressure is reduced and the cycle
  starts over again

FACTORS FOR SUCCESSFUL PROJECTS

• Constant demand for hot water
• High energy costs (diesel, LPG, electric
  resistance boiler)
• Reliable conventional energy supply
• Design storage to limit operation during peak
  charge time
• Maintenance similar to any refrigeration system
• Life cycle 15 years or more with correct
  maintenance

CONFIGURATION AND INSTALLATION

COMMERCIAL APPLICATIONS

• Industries requiring hot water for processes
• Hotels, apartments
• Health centers hospitals
• Restaurants
• Sport facilities, schools, shower facilities
• Free cooling to useful area

IN CONCLUSION

• Based on data provided on its Thermal Energy
  Questionnaire and on site survey, for each hotel
  or building, Contained Energy determines
• The most suitable SWHS, heat pump and other
  equipment configuration
• The cost savings and return-on-investment
  generated by the proposed solution
• Contained Energy then offers
• To supply and install the system, including data
  logging device
• Split payments and rental/maintenance options
• Training and after sales services
• With ROI of mostly less than a year, there is no
  more time and money to waste!
