In the cooling circuit (2), the heat sources (3a, 3b) and the radiator (4a, 4b) are connected in series with one another. A hydraulic switch (6) divides the cooling circuit (2) into two partial circuits (2a, 2b). The respective partial circuit (2a, 2b) each includes the respective heat sources (3a, 3b) and the respective radiator (4a, 4b).

The invention also relates to a method for operating the cooling system (1).

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.

A device for realizing a cooling effect in a space comprises: a housing with a heat-conducting wall, which housing bounds a chamber through which air can flow; an air inlet which connects to the chamber and to said place, —an air outlet connecting to the chamber; air transport means for transporting air from the air inlet via the chamber to the air outlet; and moistening means for moistening the inner surface of the wall; this such that air supplied by the air transport means is introduced into the chamber via the air inlet, passes along the moistened inner surface of the wall in the chamber and is discharged from the chamber via the air outlet, whereby the water present on the inner surface of the heat-conducting wall evaporates and is entrained by the air flowing by, and the wall is cooled.

A car having a water box comprising an outer face, an inner face, an air inlet opening, an air outlet opening and a water outlet opening. The inner face forms a water separating space that is connected to the air inlet and outlet openings and the water outlet opening. The water outlet opening discharges water out of the separating space. An air conditioner is connected to the air outlet opening to feed air from the water box into the air conditioner. An air feeding unit sucks the air into the air conditioner via the air inlet opening. The air feeding unit is designed as a suction fan. The water box comprises a wall that comprises fibers forming a non-woven fabric i.e. felt.

The refrigeration system is configured to adjust a temperature inside a vehicle compartment of the transport vehicle, the refrigeration system including an evaporator disposed in the vehicle compartment and the evaporator including evaporator coils (120) through which a refrigerant flows and a housing (110) for accommodating the evaporator coils; wherein the housing is further provided with a heating element (130); and the refrigeration system further includes a control module (140) configured to control the heating element. According to the refrigeration system for a transport vehicle, the control method thereof and the transport vehicle of the present disclosure, by disposing the heating element inside the housing of the evaporator, which is controlled to perform heating and stop heating according to actual situations, ice is prevented from being formed on the inner side of the housing, and condensation water is prevented from being formed on the outer side of the housing, thereby effectively improving the reliability of the preservation of goods.

A vehicle accessory power management assembly includes a vehicle speed sensor, an accelerator sensor, an accessory device, a power transmitting device and a controller. The power transmitting device receives rotational power from a power device and transmits it to the accessory device. The power transmitting device is switchable between a first operating state and a second operating state. In the first operating state the accessory device is operated at a first power consumption level and in the second operating state the accessory device is operated at a second power consumption level lower than the first power consumption level. The controller is configured to switch the switching part from the first operating state to the second operating state in response to determining that a current level of acceleration requested of the power device is of greater importance than operating the accessory device at the first operating state.

The invention relates to a method for transporting heat-sensitive products in a refrigerated lorry of the indirect injection type, wherein the temperature T.sub.int inside the storage chamber is regulated by varying the pinch of the exchanger (Pinch=T.sub.int−TFluid outflow) according to the position of the internal temperature T.sub.int in relation to a temperature set value.

Nebulizer systems to generate a mist of micro-droplets of a liquid for the purpose of freshening the atmosphere. Nebulizer systems having a small size that can be mounted on a sales stall to humidify and freshen fresh products displayed for sale, or in a vehicle to humidify and freshen the air and make it pleasant to breathe.

An adsorption system can be used as part of a climate control system in a vehicle or in any other space requiring heating or cooling. The adsorbent system can include an enclosure, a plurality of layers arranged in a stack inside the enclosure, and a vapor channel inside the enclosure.

An environmental control system includes a refrigerant circuit with a pump segment and an evaporator segment, an evaporator arranged along the evaporator segment and in fluid communication with of the refrigerant circuit, and a coolant circuit. The coolant circuit extends through the evaporator and is thermally coupled to refrigerant circuit by the evaporator, the coolant circuit including a first segment and a second segment arranged in parallel with one another to transfer heat from a first zone to a first portion of liquid coolant traversing the coolant circuit and transfer additional heat from a second zone to a second portion of coolant traversing the coolant circuit. Aircraft and environmental control systems are also described.
