An object of the present invention is to provide a vehicular air conditioning apparatus capable of varying the temperature of air that has passed through a heater core in the up-down direction of the heater core while achieving downsizing. The vehicular air conditioning apparatus includes an electric heater (43) that is provided in a flow channel defined by a housing on the downstream side of an evaporator, that includes heater circuits (48, 49), and that configures a heater core (17) that heats air cooled by the evaporator, and a control device (25) that separately controls the heater circuits (48, 49). The heater circuits (48, 49) are arranged in the up-down direction of the heater core (17).

A cooling medium distribution apparatus includes a valve housing having a valve body, a plurality of through-holes, and a plurality of distribution channels communicating with the respective through-holes, the plurality of distribution channels allowing a cooling medium to be distributed; a reservoir tank that communicates with the distribution channels, the reservoir tank storing or distributing the cooling medium; and a water pump that communicates with the through-holes and the distribution channels, the water pump distributing the cooling medium through the plurality of through-holes depending on a rotational position of the valve body. The cooling medium distribution apparatus may be installed in a vehicle to distribute the cooling medium to various cooling system parts.

Problem to be Solved To provide a heat exchanger that can increase the performance by setting an optimal number of tube groups in a configuration where each of the tube groups is provided with headers. Solution The number of arrays of tube groups of a core section 2 is set to three rows. The number N of heating medium flow holes 21 per tube is set for each width dimension Tw of tubes 20, and the tubes 20 are formed such that the width dimension Tw of the tubes and a flow channel cross-sectional area S satisfy a relationship of S1SS2. Therefore, the number of arrays of the tube groups in the core section 2 can be set to an optimal number of arrays for improving the endothermic capacity and reducing the weight, and sufficient refrigerant flow rate and pressure resistance can be secured. As a result, even when there is a restriction on the size of the entire heat exchanger, a light high-performance heat exchanger can be configured. This is significantly advantageous when the heat exchanger is used as an evaporator of a vehicle air conditioning apparatus for which a reduction in the weight of the components and an increase in the performance are demanded.

An HVAC air inlet housing for a vehicle includes an air inlet housing having a top portion and a bottom portion. A fresh air duct, to convey fresh air from an air inlet to a blower, is defined by the air inlet housing. A water inlet port, to connect to an evaporator drain port via a hose, is defined in the bottom portion. The hose is to convey water from the evaporator drain port to the water inlet port. A water tunnel is defined by the air inlet housing to convey water from the water inlet port to a sluice defined in the bottom portion. The sluice is to convey water from the water tunnel to a sump defined in the bottom portion. A sump drain port is defined in the air inlet housing bottom portion in fluid communication with the sump to drain water from the sump.

The present disclosure relates to apparatuses/systems and associated methods for controlling an environmental condition inside a container or housing. The apparatus includes (1) a thermoelectric cooling unit having a first side facing away from an inner surface of the housing and a second side facing the inner surface of the housing; (2) a capillary unit having a first part and a second part; and (3) a sensor positioned inside the housing and configured to sense a humidity value and a temperature value inside the housing. The first part is coupled to the thermoelectric cooling unit and is positioned inside the housing. The second part is positioned outside the housing. If the humidity value is greater than a humidity threshold and the temperature value is greater than a temperature threshold, the thermoelectric cooling unit removes moisture in the housing, and the first part of the capillary unit collects the removed moisture and transmits the removed moisture to the second part of the capillary unit.

A vehicle air conditioner to be installed in a passenger compartment S includes a casing, a piping component, and a seal 60. The casing accommodates a heat exchanger. The piping component supplies a heating medium to the heat exchanger or exhausts the heating medium from the heat exchanger. The seal 60 seals a portion between the casing and a periphery of an opening P of a dash panel P of a vehicle. The dash panel P separates the passenger compartment S from an outside of the passenger compartment S. The piping component is inserted into the opening. The seal 60 has a surface facing the dash panel P and including a notch 60d. The notch 60d is positioned outside the periphery of opening P1.

Provided is a refrigerant container having a rational structure with a small number of components, the container having both the functions of a receiver and an accumulator. Specifically, the refrigerant container includes a tank 10 capable of temporarily storing a refrigerant; and a gas/liquid inlet port 15, a liquid-phase outlet port 16, and a gas-phase outlet port 17 that are provided in an upper portion of the tank 10. The refrigerant container 1 is adapted to separate a refrigerant introduced through the gas/liquid inlet port 15 into a liquid-phase refrigerant and a gas-phase refrigerant, and has the function of a receiver that guides only the liquid-phase refrigerant after the separation to the side of an expansion valve via the liquid-phase outlet port 16, and the function of an accumulator that guides the gas-phase refrigerant after the separation to the suction side of a compressor via the gas-phase outlet port 17 together with oil contained in the liquid-phase refrigerant.

A vehicle system includes a refrigerant loop with a specific arrangement of valves and evaporators or heat exchangers to reduce the number of valves necessary. The vehicle system includes a refrigerant loop that includes a first thermal expansion valve downstream of a condenser and upstream of a first evaporator. A second thermal expansion valve is downstream of the condenser and upstream of a second evaporator. A third thermal expansion valve is upstream of a battery chiller. This arrangement allows for the valves to be simplified such that none of the thermal expansion valve include a binary shut-off valve. A multi-flow position valve may be positioned at a location that combines the outlet of the first and second evaporators.
