Air conditioner for vehicle


When a refrigerant evaporation temperature of an interior evaporator cannot be set lower than a dew-point temperature of air flowing into the interior evaporator in a heating operation, a refrigerant circuit is switched to a normal heating operation mode in which a flow rate of the refrigerant flowing into the interior evaporator is set to zero by allowing the refrigerant to flow toward a bypass passage. In a case where the air cannot be dehumidified by the interior evaporator, an unnecessary heat exchange between the air and the refrigerant in the interior evaporator can be suppressed.

Controlling hvac condenser fans using pressure sensors


A heating, ventilation and air conditioning (hvac) unit may both save energy and monitor for fault conditions by monitoring an ambient air temperature, compressor discharge pressure, and evaporator suction pressure and using these measurements to identify known conditions. Compressor discharge pressure and ambient temperature may be used as indices to a look up table or map to determine a speed and direction for a condenser fan.
