Title:
AIR CONDITIONER FOR VEHICLES
Document Type and Number:
WIPO Patent Application WO/2000/007836
Kind Code:
A1
Abstract:
An evaporator (13) is provided with a temperature sensor (16), and a temperature-humidity sensor (17) is installed on the upstream side of the evaporator (13). The temperature sensor (16) and the temperature-humidity sensor (17) are connected to a control unit (20). The control unit (20) determines the dew point based on the temperature and humidity measured by the temperature-humidity sensor (17), and controls the on/off of the compressor (30) to regulate the flow of coolant so that, when the dew point is between 0 and 3 °C, the temperature of the evaporator (13) measured by the temperature sensor (16) may be about 2 °C higher than the dew point.
