    摘要： In order to shift a rotation angle of a rotor to a region of a normal mode (for example, a region c) from a region of a heater cut mode (for example, a region e), the rotation angle needs to pass through a region where a flow rate of a refrigerant which is caused to flow through all branch channels becomes zero (a region d). When the refrigerant has a high temperature, there is a possibility of the refrigerant being not cooled, and boiling. Therefore, when a request to switch a normal mode and a heater cut mode is issued, permission/non-permission of switch of the mode is determined by comparison of a temperature of the refrigerant detected by the temperature sensor 26 and an upper limit temperature of the refrigerant.

    摘要： A wireless system for monitoring and control of the temperature of a product in transport includes a controller system wirelessly connected to a temperature system and a valve control system. The temperature system measures the current temperature of the product and wirelessly transmits the temperature information to the controller system. The valve control system controls the position of a valve allowing heated fluid to move through the product, heating the product. The controller system allows an operator to input a high temperature limit and low temperature limit and alarm, and using the current temperature of the product, wirelessly signals the valve control system to open or close the valve in order to keep the temperature of the product between the high temperature limit and low temperature limit. The controller system monitors and records the product temperature, high and low temperature limits and alarms, and provides a report of the data.

    摘要： A vehicle cooling system includes: an adsorption refrigerating machine having an adsorber that includes an evaporation-condensation section housing a first refrigerant, the adsorption refrigerating machine being configured to cool a third refrigerant that circulates between the evaporation-condensation section and a cooler core with evaporative latent heat of the first refrigerant; a second refrigerant flow passage through which flows a second refrigerant that circulates between the adsorption section and a radiator; a bypass flow passage that bypasses the radiator; a valve that is provided at a junction of the second refrigerant flow passage with the bypass flow passage on a downstream side of the radiator; and a valve controller configured to control the opening and closing of the valve based on the temperature of the second refrigerant.
