  • the heat pump comprises an inlet called “cold inlet” and an outlet called “hot outlet”, connected to the heat transfer module, and its function is to heat the flow of water circulating between the cold inlet and the hot outlet.
  • the heat transfer module comprises a heat exchanger having an inlet called “hot inlet” connected to the hot outlet of the heat pump and an outlet called “cold outlet” connected to the cold inlet of the heat pump.
  • the exchanger also comprises an inlet called “cold inlet” connected to the bottom part of the tank and an outlet called “hot outlet” connected to the top part of the tank via a first three-way valve device.
  • the first three-way valve device is connected to the top inlet of the tank by its first channel called the “outlet” channel, to the cold inlet of the heat exchanger by its second channel called “bypass channel” and to the output heat exchanger through its third channel called the inlet channel.
  • the water circuit circulating in the heat pump which supplies the calories during the heat exchange, is called the primary circuit.
  • the water circuit circulating between the tank and the exchanger, which receives the calories supplied by the primary circuit is called the secondary circuit.
  • thermodynamic systems on the market have combined small tank volume capacities with low so-called “conventional” heat pump powers, that is to say using HFC or HCFC type refrigerants. allowing a temperature rise of 5 to 8 ° C after heating the water by the heat pump. Consequently, this type of system is only suitable for individuals or small apartment buildings, via a so-called “accumulation” mode of production in which hot water is stored in the tank.
  • thermodynamic systems are intended for the direct production of domestic hot water (DHW) for tertiary sectors, collective residential dwellings and small and medium industries.
  • DHW domestic hot water
  • these domestic hot water production systems do not allow temperature regulation on the secondary circuit.
  • Carbon dioxide (CO2, referenced in a known manner R744) is a fluid without harmful effects on human health and healthy for the environment. It is a natural refrigerant with very low global warming power (GWP of the order of 1) compared to the HFCs or HCFCs traditionally used (which has a GWP 1300 to 2000 times higher).
  • GWP global warming power
  • a CO 2 heat pump can directly produce hot water up to 90 ° C, unlike conventional HFC / HCFC heat pumps which only produce hot water up to a temperature of around 60 ° C.
  • a CO 2 heat pump makes it possible to optimize energy efficiency and ensure the calorific power (constant) down to very low outside temperatures according to the principle known to those skilled in the art under the name "inverter”.
  • the inverter principle consists of starting the heat pump gradually, starting to decrease the intensity while maintaining the temperature with a low speed of rotation of the compressor just before the set temperature in order to consume only the necessary amount of energy, this which allows the heat pump to adapt its power to thermal inertia and to the real need for heat in the installation.
  • a CO 2 heat pump being able to work without (electrical) back-up up to low ambient temperatures makes it possible to improve the overall energy balance of the thermodynamic system. It is therefore a high energy efficiency system that generates low operating costs.

  • the CO 2 heat pump For the durability and reliability of the CO 2 heat pump, the required water quality is demanding and must be controlled. In addition, after each draw-off and with the addition of cold water in the tank (reservoir), the CO 2 heat pump restarts. However, the CO 2 heat pump needs a certain time for it to be able to establish its stabilized operating regime according to the inverter principle. During this time, the water temperature at the outlet of the CO 2 heat pump being variable and often lower than the set value, this thus causes the de-stratification of hot water in the tank.
  • the PAC CO 2 must be able to perform operations such as a defrost or anti-freeze cycle.
