Exchangers

BRAZED PLATE SOLAR HEAT EXCHANGER

Solar domestic hot water

The brazed plate heat exchanger are designed to transfer the heat energy from the solar circuit to the domestic hot water secondary circuit. Heat transfer is carried out by a counter-current circulation of primary and secondary fluids on each side of the heat exchanger. This counter-current circulation maximizes the energy transfer and homogenizes the temperatures.

Technical description

Technical specifications:

  • Dimensioning assumptions for solar heat exchangers are the following:
  • Exchanger power based on 650 W/m²
  • Head loss max 20 kPa (2mWC)
  • Minimum 10% margin over-power
  • Flat-plate collector: Primary = MPG (Profile 60/36°C) / Secondary Clear Water (Profile 27/55°C)
  • Vacuum tube collector: Primary = MPG (Profile 60/44.5°C) / Secondary Clear Water (Profile 39/55°C)
