Embodiment Construction

[0023]As shown in FIG. 1, a vehicle air-conditioning system 10 according to an embodiment of the present invention has a duct 14 defining a passage 12 therein for discharging temperature- and humidity-regulated air into the passenger's compartment of a vehicle. The vehicle air-conditioning system 10 includes a blower 16 disposed in the duct 14 at a position upstream with respect to the direction in which air flows in the passage 12, i.e., in the direction indicated by the arrow X, and an evaporator (cooling heat exchanger) 18 disposed in the duct 14 downstream of the blower 16. A heater core (heating heat exchanger) 20 is in the duct 14 downstream of the evaporator 18. An air-mixing mechanism 22 for mixing cool air and hot air with each other is mounted in the duct 14 on an inlet side of the heater core 20.

[0024]As shown in FIG. 2, the evaporator 18 includes fins 24 in which a coolant (temperature-regulating medium) flows. The evaporator 18 evaporates the coolant by allowing heat to...

Abstract

A vehicle air-conditioning system includes a duct housing therein an evaporator, an air-mixing mechanism, and a heater core that are successively arranged along the direction in which air is delivered by a blower to flow through the duct. A temperature sensor for detecting the temperature of the evaporator is disposed upstream of the evaporator with respect to the direction in which the air flows through the duct. The temperature sensor has at least a portion inserted in the evaporator.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a vehicle air-conditioning system having a duct for discharging regulated air into the passenger's compartment of a vehicle, the duct housing therein a heat exchanger for performing heat exchange between air and a temperature-regulating medium which flow in the duct.[0003]2. Description of the Related Art[0004]Usually, vehicle air-conditioning systems include a temperature sensor for measuring the temperature of air immediately after the air has passed through a heat exchanger such as an evaporator or the like for the purpose of preventing the heat exchanger from being frozen.[0005]For example, as shown in FIG. 8 of the accompanying drawings, a vehicle air-conditioning system disclosed in Japanese Laid-Open Patent Publication No. 2003-300410 has a casing 2 defining therein a passage 1 for discharging regulated air into the passenger's compartment of the vehicle. The vehicle air-condition...
