A heat pump and air conditioning system for a vehicle that has at least one coolant loop selectively connecting an engine cooling system with a heater core, a first coolant/refrigerant heat exchanger, and/or a second coolant/refrigerant heat exchanger, in order to warm a passenger compartment of the vehicle. The system also includes a refrigerant loop that includes a first expansion device between a condenser and evaporator, and a second expansion device between the first coolant/refrigerant heat exchanger and the second coolant/refrigerant heat exchanger. The refrigerant loop provides for cooling of the passenger compartment of the vehicle, as well as operating as a heat pump, together with the at least one coolant loop, to provide heat to the vehicle passenger compartment.

Heat pump and air conditioning system for a vehicle

This invention provides an auxiliary heating and cooling circuit for an automobile interior compartment. The auxiliary circuit uses a circulated liquid heat transfer fluid such as the same liquid used for the vehicle engine system. In a cooling mode, the liquid is circulated through a heat exchanger within the vehicles air-conditioning circuit. The cooled fluid flows to an auxiliary heat exchanger where cooled air is made available. In a heating mode, the auxiliary system is connected directly with the engines cooling system where the hot engine coolant flows through the auxiliary heat exchanger for interior compartment heating.

System for air conditioning of the interior of an automobile

The invention relates to a refrigeration system for an air conditioner of an automobile, the system having at least a gas cooler, an evaporator, and an expansion valve assembly. The expansion valve assembly is provided with an expansion chamber that is in fluid communication with the gas cooler and the evaporator. A valve defines an opening from the expansion chamber to the outlet conduit and a diaphragm defines another boundary of the expansion chamber. An appendage at least partially located within the expansion chamber. A variable-force mechanism is adapted to cause movement of an appendage coupled thereto, and it is at least partially controlled by an electrical signal. An appendage is moved by the variable-force mechanism, resulting in throttling of the opening.

Method and system for electronically controlled high side pressure regulation in a vapor compression cycle

An evaporator and method of making same includes a first end tank, a second end tank spaced from and opposing the first end tank, and a plurality of extruded fluid carrying tubes extending between and in fluid communication with the first end tank and the second end tank. The first end tank and the second end tank are formed as stampings.

Evaporator and method of making same

A carbon dioxide/cofluid mixture is provided for use in a refrigeration cycle in which the carbon dioxide is alternately absorbed and desorbed from the cofluid. The mixture includes from 50% to 95% cofluid and from 5% to 50% carbon dioxide. The cofluid is selected so that the mixture falls within region A of the plot of p versus &Dgr;h shown in FIG. . The &Dgr;h of the mixture is the differential heat of solution of the carbon dioxide in the cofluid at 5 wt % and 0&deg; C. The p of the mixture is the vapor pressure of the carbon dioxide over the solution at 20 wt % and 40&deg; C.

A condenser having an integral receiver dryer includes a first manifold, a second manifold, and a plurality of fluid carrying tubes extending between and in fluid communication with the first manifold and second manifold. The condenser also includes a receiver dryer being internal to and integral with a housing of one of the first manifold and the second manifold and including a dryer material disposed in the housing to dry fluid therein.
