Abstract

<P>PROBLEM TO BE SOLVED: To reduce a consumption power of vapor compression refrigerator while promoting warm-up. <P>SOLUTION: When a temperature of cooling water is high, an absorbing body 5 is heated by the cooling water and water vapor is eliminated to accumulate a heat. When the temperature of cooling water is low, water vapor is adsorbed to heat the cooling water by an adsorption heat while water is evaporated and a cooling medium of the vapor compression type refrigerator 8 is cooled. Thereby, while a promotion of the warming up is realized, a consumption power of the vapor compression type refrigerator can be reduced. At this time, since an evaporation latent heat of water is large, i.e., 2,500 kJ/kg, a heat accumulator comprising an absorption chamber 4 and a liquid storage chamber 10 can be made small. <P>COPYRIGHT: (C)2003,JPO

蒸発し続ける。At this time, when the absorber 5 adsorbs the vapor medium in the absorption chamber 4, the pressure in the absorption chamber 4 becomes lower than that in the liquid storage chamber 10, and in this state, the vapor compression refrigerator 8
Is activated, the ambient temperature in the liquid storage chamber 10 becomes a temperature according to the refrigerant temperature (for example, 40 ° C. to 60 ° C.), and the ambient temperature in the absorption chamber 4 becomes a temperature according to the outside air temperature (for example, 25 ° C.). Therefore, the liquid phase medium in the liquid storage chamber 10 absorbs heat from the refrigerant via the condensing core 9 and continues to evaporate.

下し過ぎることを未然に防止する。After the warm-up operation is completed, the valve 1
You can leave 2 open. With this configuration, for example, when the idling operation is stopped, the rotation speed of the engine 1 and the traveling air volume decrease, and the heat load of the vapor compression refrigerator 8, that is, the cooling capacity of the condenser 8b decreases. Since the load of 1 decreases and the cooling water temperature decreases, the warming / auxiliary cooling mode is automatically set to reduce the power consumption of the vapor compression refrigerator 8 while the cooling water temperature decreases too much. Prevent things from happening.

This is a mode in which cooling assistance is performed in a state where the temperature reaches a temperature at which the cooling can be performed.
