Title: Car air conditioner
Inventor: SAKAKIBARA NAOJI
IPC: B60H1/00
Filed: 1980-09-20
Abstract: PURPOSE:To soften the thermal shock of a driver and prevent excessive cooling or heating in a car conditioner by enabling each person to set a desired temperature difference between outer and inner air. CONSTITUTION:An outer temperature sensor signal is inputted into a setting unit of the temperature difference to an inner temperature and a comparison circuit. From a temperature difference setting unit, a corresponding car room temperature based on an outer temperature and the set value of a desired temperature difference is outputted. The output is sent into a comparison computation circuit to be compared with an inner temperature sensor signal via a switching unit, and a damper control system is controlled on the basis of that deviation. When the outer temperature is specially high and the inner temperature can not be set within a fixed set temperature difference, the direct input of the outer temperature sensor signal is subjected to compensation. Besides, the temperature difference setting process can be switched over to an inner temperature setting unit free from the temperature difference from the outer temperature via the switching unit.
