International Classification:

B60H 1/00
F25B 13/00

US Classification:

165202, 623241, 623242, 623246

Abstract:

An HVAC system for heating and cooling a passenger compartment of a vehicle includes a first heat exchanger that transfers heat between a primary loop and a secondary loop. The primary loop is a reversible loop and uses high pressure refrigerant. A compressor pressurizes the refrigerant. A second heat exchanger selectively transfers heat energy to and from the passenger compartment. The secondary loop is a low pressure liquid coolant loop that passes through the first heat exchanger. A pump moves fluid through the secondary loop. A third heat exchanger transfers heat to and from an external medium from the fluid passing through the secondary loop. A secondary heat source adds heat to the secondary loop during a heating mode. A bypass means selectively bypasses the secondary heat source during a cooling mode.

International Classification:

F25B 27/00

US Classification:

623233

Abstract:

An air conditioning system for cooling an environment in an over-the-road vehicle is provided. The air conditioning system includes an electrically driven, variable speed compressor, which enables operation of the system when the engine of the over-the-road vehicle is not running. The system is modular and is adapted to be installed in the side luggage compartment of the vehicle to enable existing vehicles to be retrofitted to provide no-idle air conditioning. The housing of the system defines two flow paths therethrough; one cold air path and one hot air path. The hot air path is configured to intersect the condenser at least two times, and draws and expels the air through the same wall of the housing. An air direction device is used to reduce the amount of air recirculation through the hot air path to increase the efficiency of the system.

Appl. No.:

15/791243

Inventors:

- Rockford IL, US
Brett Sean Connell - Winnebago IL, US

International Classification:

B60H 1/00

Abstract:

The disclosed embodiments include a vehicular ventilation module having control circuitry, a return air duct, a fresh air duct, a heat exchanger, and a door joining an upstream portion of the return air duct upstream of the heat exchanger and an upstream portion of the fresh air duct upstream of the heat exchanger. The fresh air duct has an air inlet and an air outlet downstream of the air inlet. The heat exchanger is thermally coupled to the return air duct upstream of the return air outlet and to the fresh air duct downstream of the return air inlet. The door selectively opens to enable air to pass between the fresh air duct and the return air duct. The control circuitry is configured to operate in a first mode of operation, including having the door open. The return air outlet is configured to provide air to the HVAC system.

International Classification:

B60H 1/32

US Classification:

623231, 62434, 62335

Abstract:

A vehicle air conditioning system is provided. The vehicle air conditioning system includes a first vapor compression refrigeration loop. The first vapor compression refrigeration loop includes a first refrigerant compressor and a first evaporator. The vehicle air conditioning system further includes a tank for holding a compressed fluid, an outlet configured to carry expanded fluid from the tank, and a heat exchanger thermally coupled to the first vapor compression refrigeration loop and to the outlet. The heat exchanger is configured to transfer heat from refrigerant carried by the first vapor compression refrigeration loop to fluid carried by the outlet, where the temperature of the fluid carried by the outlet has been reduced as a result of expansion of the fluid upon exiting the tank.

Abstract:

The vehicle ventilation module includes a return air duct, a fresh air duct, a heat exchanger, and first and second doors. The return air duct has a return air inlet and a return air outlet downstream of the return air inlet. The fresh air duct has a fresh air inlet and a fresh air outlet downstream of the fresh air inlet. The heat exchanger thermally coupled to the return air duct and the fresh air duct. The heat exchanger is upstream of the return air outlet and the fresh air outlet, and downstream of the return air inlet and the fresh air inlet. The first door joins the return air duct and the fresh air duct upstream of the heat exchanger. The second door joins the return air duct and the fresh air duct downstream of the heat exchanger. The first door and the second door are operable to selectively open and close in order to allow air to pass between the fresh air duct and the return air duct.
