A cold storage heat exchanger includes: a plurality of refrigerant tubes disposed at intervals, each of the refrigerant tubes including a refrigerant passage that allows a refrigerant to flow therethrough; a cold storage material adjacent to the refrigerant tubes; and a heat transfer suppressor that suppresses heat transfer from the refrigerant tubes to the cold storage material in an overheated area of the refrigerant formed in the refrigerant passage.

Cold storage heat exchanger

A refrigerant evaporator has an interchange part. The interchange part connects a first collecting part of a second downstream tank part, and a second distribution part of a second upstream tank part. The interchange part connects a second collecting part of a second downstream tank part, and a first distribution part of a second upstream tank part. The interchange part swaps a refrigerant about a width direction of a core. Refrigerant passages relevant to the interchange part are configured to improve refrigerant distribution. Providing a plurality of passages and/or twisting a passage improve distribution.

Refrigerant evaporator

An air conditioner for automotive vehicles is disclosed. The flow rates of air supplied to an evaporator () and a heater () are adjusted by rotationally displacing a scroll casing () and thus changing an air flow from a blower () to a predetermined direction. The air-mix door can thus be eliminated to allow a smaller size of an air-conditioner casing () (air-conditioning unit ()). Also, the ratio between cool air flow rate and hot air flow rate is adjusted by rotationally displacing the scroll casing () with a spur gear () and, therefore, the size and the production cost of the air conditioner can be reduced as compared with a conventional system in which an air-mix door is swung by a link mechanism.

Air-conditioning unit without air-mix door

An upper opening portion () and lower opening portion () are arranged in a door body () located below a side window (), and an air conditioning unit () is arranged inside the door body (), and a rotary position of a scroll casing () of a blower () is selected so that air can flow from the lower opening portion () to the upper opening portion () at the time of air-cooling and air can flow from the upper opening portion () to the lower opening portion () at the time of heating.

Air conditioner for vehicle use

A blower unit of an air conditioning unit including a scroll casing including a first engaging portion, a fan casing including a first engaging portion, and a controller for controlling an electric motor to move at least one of the scroll casing and the fan casing such that the movement of at least one of the scroll casing and the fan casing stops when the first engaging portion of the scroll casing abuts the first engaging portion of the fan casing. The precision of the position of the scroll casing with respect to the fan casing, the precision of the temperature of air discharged into the compartment, and/or the volume of the blower unit may be improved.

Blower unit and air conditioning unit including the same and method of controlling the same

In a left and right temperature independent control-type air conditioning unit for a vehicle, a case is constructed of a first case and a second case. An air passage in the case is divided into a first air passage through which air flows toward a right region of a compartment and a second air passage through which air flows toward a left region of the compartment by a partition wall. The first and second cases are connected by engaging a first case end surfaces with a second case end surface. Pin contact portions are formed on the first and second cases adjacent to the case end surface. The pin contact portions are disposed to oppose each other between the first case and the second case. The partition wall is fixed by interposing its periphery between the pin contact portions of the first and the second cases.

Vehicular air conditioning unit

An air conditioning apparatus for a vehicle has a first side opening portion and a second side opening portion for blowing air toward right and left sides of a passenger compartment. A cool air passage and a warm air passage are provided adjacently to extend in a vehicle width direction, and the first and second side opening portions are arranged to be perpendicular to the vehicle width direction. A three-way branch duct is attached to the air conditioning apparatus in such a manner that air introduced into the first side opening portion is blown toward a right side of the passenger compartment and air introduced into the second side opening portion is blown toward a left side of the passenger compartment. Thus, a temperature difference between air blown from the right side and air blown from the left side of the passenger compartment can be reduced.
