Method for evaporator temperature control as a function of the outside dew point
First Claim
1. A method for controlling an evaporator temperature of an air conditioner as a function of the outside dew point, comprising the acts of:
- determining an air temperature (TA) and a dew point temperature (TP) of incoming air drawn in from outside by the air conditioner;
determining an evaporator demand temperature (TVA) without reheating from an interior temperature setpoint information;
setting the evaporator temperature (TV) to a setpoint (TVS); and
choosing the setpoint (TVS) within presettable temperature limits as the smaller value of the evaporator demand temperature (TVA) and the difference between the air temperature (TA) and the dew point temperature (TP) of the incoming air.

Abstract
A method for controlling the evaporator temperature of an air conditioner as a function of the outside dew point, in which the air temperature and the dew point temperature of the incoming air drawn in from outside by the air conditioner for air conditioning an interior are determined. An evaporator demand temperature without reheating is determined from the interior temperature setpoint information. On the one hand, the evaporator temperature is set to a setpoint that, within presettable temperature limits, is selected as the smaller value of the evaporator demand temperature. On the other hand, the evaporator temperature is set to a setpoint that, within presettable temperature limits, is the difference between the air temperature and the dew point temperature of the incoming air on the other. A typical use of the method, for example, is in the air conditioners of motor vehicles.
