Problems solved by technology

[0009] As mentioned above, in the existing technology, when maintaining the expansion valve block located on the front wall or side wall of the air conditioning unit, the expansion valve block cannot be simply taken out.
That is, without taking out the air supply unit and the air conditioning unit from the vehicle body, only the expansion valve block cannot be taken out, and maintenance of such an expansion valve block is not considered at all.
[0010] In addition, the following technology has been disclosed: when replacing the evaporator as a cooling heat exchanger, in order not to take the air conditioning unit out of the car, a part of the air conditioning box is provided as a cover member, and the cover member is removed to remove the evaporator. take out the evaporator, as described in Japanese Patent Laid-Open No. 10-81123, but in this case, where the expansion valve block is arranged at the end of the evaporator, and how to take it out etc., and the installation of the expansion valve block has not been made public

Abstract

The invention relates to an air conditioner (1), in which air introduced into an air conditioning unit (4) flows through an evaporator (30) and a heater core (31) disposed in the unit (4) respectively, an expansion valve block (33) disposed at a side wall of the air conditioning unit (4) is disposed directly at the side wall of the air conditioning case (20) that is located at driver-seat side.

Description

Technical field [0001] The present invention relates to an air conditioner for a vehicle, and particularly relates to a design structure of an expansion valve of a cooling heat exchanger provided in an air conditioning unit. Background technique [0002] So far, regarding this type of vehicle air conditioner, Japanese Patent Laid-Open No. 2000-25447 has disclosed the following technology: an air-conditioning unit is arranged near the center in the vehicle width direction in the instrument panel, and the air conditioning unit is placed in the passenger seat of the instrument panel. One side is equipped with a blower unit. The cooling heat exchanger and the heating heat exchanger are housed in the box of the air conditioning unit. The cooling piping (cooling medium piping) is connected to the side wall on the passenger seat side of the air conditioning unit. The evaporator is connected, the cooling pipe is bent at a right angle and extends forward, and an expansion valve block is p...
