      Supervision of light radiation of oil flames in the visible range of the light spectrum. The light-sensitive element is a photo resistor whose electrical dark resistance lies in the M range. As the intensity of light increases, the electrical resistance drops to the k range and is evaluated by the burner control for generating the flame signal. In contrast to the photocell ot the RAR, glowing firebrick in the combustion chamber can be detected.

      Why the air-conditioning supplyreturn water temperature is 7℃-12℃

      08/21/2020

      Why the air-conditioning supplyreturn water temperature is 7℃-12℃

      Reason analysis of 7 degree water supply:    1. Starting from the refrigeration unit, the refrigerant evaporates in the evaporator and absorbs heat to cool the secondary side water. If the evaporation temperature is too low, it will cause frost on the surface of the evaporator and affect the heat transfer efficiency.
