An air conditioner of an electric vehicle according to the present invention includes a compressor for compressing refrigerant, an indoor heat exchanger for performing heat exchange between refrigerant introduced into the indoor exchanger after emerging from the compressor and air, an outdoor heat exchanger for performing heat exchange between refrigerant introduced into the outdoor heat exchanger and outdoor air, a first expansion device arranged between the indoor heat exchanger and the outdoor heat exchanger, to expand refrigerant introduced into the first expansion device, an evaporator for evaporating refrigerant introduced into the evaporator, to dehumidify indoor air, a second expansion device arranged between the outdoor heat exchanger and the evaporator, to expand refrigerant introduced into the second expansion device, a first bypass line connected to guide refrigerant emerging from the indoor heat exchanger to flow toward the evaporator after bypassing the first expansion device and the outdoor heat exchanger, and a second bypass line connected to guide refrigerant flowing toward the evaporator to flow toward the compressor after bypassing the evaporator. During a heating operation, the first bypass line is selectively used in accordance with an outdoor temperature, and the second bypass line is selectively used in accordance with an indoor humidity..
|Orc heat engine|
An orc heat engine including a working fluid circuit having an evaporator for heating and evaporating a working fluid, a condenser for cooling and condensing the working fluid, and a positive displacement expander-generator having an inlet in fluid communication with the evaporator and an outlet in fluid communication with the condenser. The orc heat engine further includes a control system coupled to the positive displacement expander-generator having a switch and driving means, the switch being switchable between a first state and a second state, wherein in the first state the switch is coupled to the driving means, and the positive displacement expander-generator is drivable by the driving means, and in the second state the switch is not coupled to the driving means or the driving means is switched off, and the positive displacement expander-generator is not drivable by the driving means..
|Heat pump laundry dryer|
The present invention relates to a heat pump laundry dryer (1) comprising a drum (2) wherein the laundry to be dried is placed, an air duct (3) wherein the processing air cycle is realized, a processing air fan (4) that provides the circulation of the processing air, a compressor (5) that realizes the refrigerant cycle, an evaporator (6) that provides the processing air in the air duct (3) to be dehumidified, a condenser (7) that provides the dehumidified processing air to be heated, a refrigerant line (8) that provides the refrigerant pressurized by the compressor (5) to pass through the condenser (7) and the evaporator (6) to be delivered to the compressor (5) again and a cooling fan (9) that provides the compressor (5) to be cooled.. .
