摘要:
An HVAC module for a vehicle includes a cooling unit to cool air that passes through the cooling unit and a heating unit to warm air that passes through the heating unit. The HVAC module has a housing having a plurality of airflow paths to guide the air that passes through the cooling unit or the heating unit. An upper discharge outlet temperature is indeterminate based on a temperature detected by a single temperature sensor in one of the plurality of airflow paths and a blend setting. The HVAC module includes a temperature sensor to determine a reference temperature of the air at a sensor location. The reference temperature is offset from a floor outlet temperature by a floor offset function of the blend setting. The reference temperature is offset from the upper discharge outlet temperature by an upper offset function of the blend setting.

A transport refrigeration system including a refrigerant compressor which is alternatively driven by an internal combustion engine or an electric induction motor. The transport refrigeration system achieves and maintains a predetermined set point temperature in a served space by heating and cooling cycles. When additional heat is required during a heating cycle while the internal combustion engine is driving the compressor, capacitors are connected across the induction motor, to cause the motor to function as an induction generator and build up an output voltage. The output voltage is monitored, and when it is sufficient to sustain a load, resistors located to aid the heating cycle are connected to receive the output voltage.

There is disclosed a vehicle air conditioner device which is capable of continuing air conditioning of a vehicle interior also in a case where a failure occurs in a solenoid valve to change a flow of a refrigerant in each operation mode. A vehicle air conditioner device 1 includes a solenoid valve 17 for cooling, a solenoid valve 21 for heating and a solenoid valve 22 for dehumidifying to switch respective operation modes of the vehicle air conditioner device. A controller changes and executes the respective operation modes of a heating mode, a dehumidifying mode, and a cooling mode. The controller has a predetermined air conditioning mode during failure, and failure detecting means for detecting failure of the solenoid valve. In a case where the failure detecting means detects that the solenoid valves fail in the respective operation modes, the controller selects the air conditioning mode during failure in which vehicle interior air conditioning by the operation mode is achievable, to continue the air conditioning of the vehicle interior.

A system and method for configuring parameters for a variable gaseous appliance, comprise a sensor for detecting a composition of the gaseous fuel in a fuel tank. A first set of instructions are executable on a processor for receiving a signal from the sensor and analyzing the gaseous fuel based on the Wobbe Index, methane index, and inert gas percentage, to produce a gaseous fuel analysis. A second set of instructions are executable on the processor for producing a signal for configuring parameters of the engine for running the engine based on the gaseous fuel analysis.
摘要:
A air conditioning control device is configured to estimate whether or not the temperature of refrigerant on a high-pressure side in a heat pump device is equal to or lower than a predetermined low temperature and to switch a flow path switching device to an air-heating start-up mode when it is estimated that the temperature of refrigerant on the high-pressure side in the heat pump device is equal to or lower than the predetermined low temperature and switch the flow path switching device to a normal air-heating mode when it is estimated that the temperature of refrigerant on the high-pressure side in the heat pump device is higher than the predetermined low temperature.

摘要:
A heating apparatus for a motor vehicle including a heat exchanger having a wall for separating a heated exhaust gas from a heat exchange medium, a conveyor mechanism for conveying the heat exchange medium along the wall, and a protective mechanism for protecting the heater against overheating. The protective mechanism determines the mass flow of the heat exchange medium delivered by the conveyor mechanism when the heater is actuated so that the danger of overheating the heater is reliably detected when the delivery of the heat exchange medium is dammed.
