A system for controlling fluid temperature in a thermal system includes a heat source, a heat sink coupled to the heat source, a first heat exchanger and a second heat exchanger, a first expansion valve configured to regulate the flow of coolant between the heat source and the first heat exchanger, a second expansion valve configured to regulate the flow of coolant between the heat source and the second heat exchanger, and a controller. The controller is configured to determine an operating condition of the thermal system and generate a first control signal to control the first and second expansion valves to direct the flow of coolant to the first and second heat exchangers. The first and second expansion valves are arranged in parallel to recover heat rejected from the coolant and distribute the recovered heat to the first and second heat exchangers.

A vehicle climate control system includes a thermal-adsorption heat pump driven by engine exhaust heat, the heat pump including two adsorbers asynchronously switching between adsorbing and desorbing modes, each adsorber coupled with a corresponding antifreeze tank via a plurality of refrigerant-containing wick chambers. Cold heat transfer fluid (HTF) flows through the adsorber during the adsorbing mode which causes evaporation of refrigerant from the wick chambers, thereby cooling antifreeze, whereas hot HTF flows through the adsorber during the desorbing mode which causes condensation of refrigerant at the wick chambers, thereby heating antifreeze. In this way, the thermal-adsorption heat pump may condition cabin air independent of engine coolant and without exerting a load on the engine.

An energy recovery interior heating system has a modified mechanical or electrical drive isolation system for vehicles such as trucks. This permits a standard air conditioning compressor pump to be driven from multiple power inputs thereby providing any hybrid or non-hybrid vehicle with continuous engine-on heating and/or air conditioning, limited time engine-off heating and air conditioning and two types of engine-off air conditioning temperature modulation. Another combination of the heating and air conditioning systems would permit the continuation of heating and cooling on hybrid vehicles when they are stationary and their traction batteries are fully charged and the vehicle is operating only on the electric motors for traction or work load power. This invention also provides internal combustion engine-off heating and A/C on these types of vehicles. Another embodiment uses the drive isolation system to integrate auxiliary power unit (APU) functions as part of the traction engine of over the road trucks.

Disclosed is a heating apparatus for a cabin of a construction equipment in which hot air ejected from an oil cooler is used for heating in winter while it is ejected out in summer to maximize cooling or heating efficiency of the cabin of the construction equipment. The heating apparatus for a cabin of a construction equipment includes a duct ejecting air ejected from an oil cooler provided inside an automotive body at the rear of the cabin to the outside of the automotive body, and a switching means provided in the duct to open and close, guiding the air inside the duct to the rear of the cabin if it is opened. The heating apparatus is automatically operated depending on its peripheral temperature condition to maximize cooling or heating efficiency of the cabin.

A vehicular lockup clutch-equipped transmission control apparatus is applied to a vehicle that includes a heater apparatus for heating a cabin by heat from an engine, a transmission that transfers power between the engine and a wheel, and a heat exchanger that conducts heat exchange between the engine and the transmission. The control apparatus controls a lockup clutch that is disposed between the engine and the transmission and that mechanically connects and disconnects a path of power, in accordance with a state of operation of the vehicle. The control apparatus includes a controller that determines whether a heating capability requested of the heater apparatus is at least a first predetermined level based on a parameter related to a temperature inside the cabin. If it is determined that the heating capability requested of the heater apparatus is at least the first predetermined level, the controller restricts engagement of the lockup clutch.

An automotive air conditioning apparatus 10 is provided which includes a forced water supply system 9 and a heat pump system 14. A controller 16 controls the temperature of a second heat exchanger 38 of the heat pump system 14 to a desired temperature based on a preset temperature. The controller 16 also controls the temperature of the water circulating through the heat exchanger 20 of the forced water supply system 9 to a temperature at which the quantity of heat exchange between the air heated by the second heat exchanger 38 to the desired temperature and the heat exchanger 20 of the forced water supply system is minimized. According to this air conditioning arrangement, the temperature of the vehicle interior can be promptly raised without any capability drop being caused and thus, the heating efficiency of the apparatus being well enhanced.
