PURPOSE:To provide comfortable air condition during nap through four seasons in a truck's air conditioner having a nap mode by setting the conditioner that the reduction rate of the car's room temperature which is susceptible to variation of the temperature of conditioned air with time is increased in proportion to the cold outside the car. CONSTITUTION:Receiving the signals of an interior air temperature 21, an open air temperature 22, opening 23 of an air conditioning damper 7 and the panel signals 24 of the set temperature, set flow rate of air and other information, a controller 10 controls the operation of temperature controlling elements 1-8 in accordance with a certain program. If the open air temperature stands at a certain value below 10 deg., for example, with a nap switch depressed on, the set temperature is reduced by a certain value, for example, 15 deg.C for a certain interval and thereafter, the original set temperature is shifted to another value, namely, the decrement is lessened to 10 deg.C and the value is maintained, so that the car's room temperature may be automatically varied according to the open air temperature and a comfortable nap may be thereby ensured through four seasons. |
