Title:
ABSORPTION TYPE COLD HEAT GENERATOR
Document Type and Number:
Japanese Patent JP3175040
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To enable smoothly starting the cooling operation which is proportionate to the load factor by a method wherein when the cooling-water temperature outputted by a temperature sensor at the inlet for the cooling water is below a second temperature set lower than a first temperature, a water-refrigerant proportional valve is opened fully independent of the temperature of an evaporator.
SOLUTION: A cooling water-inlet-temperature sensor 25 is provided in the vicinity of the joint between a cooling-water pipe 41 and an absorber 5 and, while the opening of a water-refrigerant proportional valve 11 is controlled without steps on the basis of the output of an evaporator-temperature sensor 17 and also on the basis of the cooling water-inlet-temperature outputted by the cooling water-inlet-temperature sensor 25. A controller 59 controls the opening of the water-refrigerant proportional valve 11 on the basis of the output of the evaporator-temperature sensor 17 and that of the cooling water-inlet-temperature sensor 25 and make the rise part at the outlet of an evaporator coil in the refrigerant-vapor pipe 51 and the connecting part of the evaporator coil in the liquid-refrigerant pipe 50 communicate through a solenoid valve 60. The water-refrigerant proportional valve 11 keeps fully closed when the cooling water-inlet-temperature is, for example, 6°C or higher and fully open when the temperature is, for example, 2°C or less.
