How does a heat pump work?

The operation is characterized by a closed-loop system with a refrigerant fluid inside (for issues of eco-sustainability today, R-32 refrigerant, also known as difluoromethane or Freon 32, is almost always used) subject to a cyclic change of state, moving from the liquid phase to vapor and back; this obviously occurs with an expenditure of electricity, as the heat pump extracts and transfers thermal energy by employing electrical energy. According to the laws of technical physics and psychrometry, there will be variations in pressure and temperature, and the heat pump takes advantage of these variations occurring at the evaporator and compressor, resulting in a very advantageous overall efficiency or coefficient of performance (COP), even exceeding 4-5. It means that for every electric kW spent, as a result you have 4-5 kW of heat output generated by the system.

 

Low Temperature Air-to-Water Heat Pumps ideal for new buildings, environmentally sustainable standards with installation of underfloor systems, suitable for heating, domestic hot water and cooling; possible integration with solar thermal.

 

The Daikin Altherma Compact indoor unit, now equipped with R32 refrigerant gas, is known for its ability to maximize the use of renewable energy sources to offer maximum performance in heating, cooling and domestic hot water production.

 

Smart storage management:

• 'Smart Grid' unit that enables efficient storage of thermal energy for space heating and domestic hot water production when there is a surplus of photovoltaic production or particularly low tariffs
• Continuous heating in defrost mode and use of stored heat for space heating
• Electronic management of the heat pump and thermoaccumulator maximizes energy efficiency, both in heating and domestic hot water production
• Top in water hygiene Maximizing the use of renewable sources by preparing for a drain-back or pressurized solar system.
  
   

Innovative and high-quality storage tank:

• Lightweight, highly insulated technopolymer storage tank
• Absence of corrosion, scaling or scale deposits
• Shockproof polypropylene inner and outer walls filled with high-quality insulation foam to minimize heat loss
• Legionella proliferation in domestic water is prevented by technical water storage and instant domestic hot water production
  
   

Technical water storage and instant domestic hot water production for maximum comfort!

 

• The indoor unit connected to a thermal storage tank enables unprecedented levels of comfort to be achieved in a domestic environment
• Instantaneous hot water production due to technical water storage, delivery of domestic hot water on demand avoiding the risk of contamination and sedimentation
• Optimal performance in domestic hot water production: highly insulated technopolymer storage tank allows perfect temperature stratification in the storage tank and offers highly efficient delivery
