摘要:
The evaporator and the condenser are disposed in a duct. First bypass passage is disposed at the side of the condenser and first air mixing damper rotates to control air bypassing amount. Further second bypass passage is formed at the side of the evaporator and second mixing damper rotates to control air bypassing amount. Cooling rate at the evaporator and heating rate at the condenser are varied so that air adjusted in proper temperature is generated and discharged from each outlets into a room. An outside heat exchanger is disposed the outside of the duct. Refrigerant flow is randomly switched among the outside heat exchanger, the evaporator and the condenser so that cooling, heating, dehumidifying, dehumidified-heating and defrosting operations are performed.

摘要:
A refrigerant evaporator for a refrigeration cycle provided with a heat exchanging unit, comprising a passageway to be cooled and a cooling passageway, and an evaporating unit for cooling the air, wherein a part of the inflowing refrigerant is divided, passed through a throttle to be reduced in pressure, and then passed through the cooling passageway of the heat exchanging unit, the inflowing refrigerant passing through the passageway to be cooled is cooled and completely changed to the liquid state and then passed into the evaporating unit, whereby the refrigerant is uniformly distributed to a plurality of refrigerant passageways of the evaporating unit.

An automotive air conditioner which conditions air making use of radiation of heat of a condenser and absorption of heat of an evaporator effectively. The evaporator 207 and the condenser 203 are disposed in a duct 100. A bypass passageway 150 is provided sidewardly of the condenser 203 in the duct 100, and a flow rate of air bypassing the condenser 203 is controlled by pivotal motion of an air mixing damper 154. Another bypass passage is provided sidewardly of the evaporator 207 in the duct 100, and a flow rate of air bypassing the evaporator 207 is controlled by pivotal motion of a bypass damper 159. Air is conditioned to an optimum blown out air temperature by varying the cooling rate at the evaporator 207 and the heating rate at the condenser 203 and is blown out to a room of an automobile from spit holes 141, 142 and 143. An outside heat exchanger is provided outside the duct 100, and a flow of refrigerant is changed over suitably among the outside heat exchanger 202, the evaporator 207 and the condenser 203 to perform cooling operation, heating operation, dehumidifying operation, dehumidifying heating operation and defrosting operation.

摘要:
In an adsorption-type refrigerating apparatus, an adsorber includes therein an adsorbent having a temperature-dependent characteristic in which an amount adsorbed in an adsorption step is larger than an amount adsorbed in a desorption step, even when a vapor pressure rate in the adsorption step is equal to or lower than a vapor pressure rate in the desorption step. Therefore, even when the cooling temperature of outside air for cooling the adsorbent increases, a sufficient cooling capacity can be obtained. In addition, a difference between the amount adsorbed in the adsorption step and the amount adsorbed in the desorption step can be made larger.

A vehicle is provided with both an electric motor and an internal combustion engine for operating the vehicle. The vehicle is further provided with a duct for discharging air into a cabin of the vehicle for controlling the temperature of the air as discharged. A heater core is arranged in the duct for heating the air passing through the duct. A sensor 9 is provided for detection of the temperature of the cooling water of the engine. When the vehicle is operated by the electric motor, the heat taken from the engine cooling water is supplied to the heat exchanger for heating the air passing through the duct when the temperature of the engine cooling water is higher than a predetermined value.
