  • Page 7: Product Features

    1.2 Product Features 1.2.1 General This product is an integrated DC inverter unit that provides cooling, heating and water heating functions and has an energy efficiency of up to 5.0. It uses R32 refrigerant and a two-stage compressor. When heating and an outdoor temperature is between −25 and 35 °C, the leaving water temperature can be between 20 and 60 °C.
  • Page 8 (3) The high-efficient plate heat exchanger greatly improves the performance of the unit. (4) The high-efficient water pump also greatly improves the performance of the unit. • All-in-one design (1) The unit can be integrated with terminal units such as the radiator, underfloor heating, fan coil (FCU), water heater, solar water heater, gas boiler, etc.
  • Page 9 (Menu page) • Smart control, powerful functions (1) The operating mode can be switched freely. In addition, holiday mode, weather-dependent mode, quiet operation timer, temperature setting timer and floor preheating can be activated based on different requirements. (2) Multiple safety features ensure much safer operation of the equipment. An additional electric heater prevents the plate heat exchanger from freezing due to a too low temperature of the water, which helps to extend the product service life and increases its safety and reliability.

  • Page 61 (5) The economizer inlet temperature sensor is used to detect the temperature at the economizer inlet after throttling the refrigerant by the electric expansion valve 2. In Heating or Water heating mode, this sensor, together with the sensor at the economizer outlet, is used to control the opening angle of the electric expansion valve 2. In Cooling mode, the electric expansion valve 2 is completely closed.
  • Page 62 Items 1 to 14 above are control parameters (signals) that come from the main unit. (15) The water temperature in the water tank is detected by sensors immersed in the water in the tank. These sensors can be divided into two groups. Group 1 is used to control the water temperature in the tank and group 2 is used to display the water temperature in the tank.

    5.3 Repair 5.3.1 Main Parts Picture Name Function It is the core of the refrigeration system, which is mainly used to convert low-temperature, low-pressure refrigerant vapour to high- temperature high-pressure vapour and then discharge it into the Compressor evaporator. Here, a two-stage compressor is used to increase the enthalpy of the refrigerant, which can greatly improve the heating performance of the unit.
  • Page 147 Picture Name Function It is used in the Heating mode and Water Heating mode, but NOT used in the Cooling mode. On the one side, it can increase the Economizer subcooling before the expansion valve, and, on the other side, it can heat the refrigerant in the heating circuit.
