<p>When performing a heating operation and the refrigerant evaporation temperature in the indoor evaporator (17) cannot be lowered to a temperature below the dew-point temperature (Tdew) of the forced air introduced into the indoor evaporator (17), the refrigerant circuit is switched during the normal heating operation mode so that the flow of refrigerant is into a bypass passage (19) and the flow rate of refrigerant into the indoor evaporator (17) is reduced to zero. In this way, unnecessary heat exchange between the refrigerant and the forced air in the indoor evaporator (17) can be suppressed. In other words, the wasteful consumption of energy by an air-conditioning system (1) for a vehicle can be effectively suppressed.</p> |
