Abstract

The absorption heat pump provided by the present invention can suppress the excessive increase in the pressure of the vapor generating portion without operating the safety valve. An absorption heat pump for generating the heat of the heated medium by absorbing the heat of the heat source fluid introduced by the absorption heat pump fluid with the absorption liquid and the refrigerant is provided with a vapor generation unit that generates steam for the heated medium supplied to the target, a pressure detection section that detects a pressure of the vapor generation section, a safety valve that is provided in a supply steam pipe or a vapor generation section that causes the vapor of the heated medium generated in the vapor generation section to flow out of the target, and a vapor discharge valve and a control means for opening the vapor discharge valve when the pressure detected by the pressure detecting means exceeds the target pressure of the vapor generating portion and is equal to or higher than the first predetermined pressure smaller than the pressure opened by the safety valve.

Description

technical field [0001] The present invention relates to an absorption heat pump, and more particularly, to an absorption heat pump capable of suppressing an excessive increase in the pressure of a steam generator without operating a safety valve. Background technique [0002] There is a second type of absorption heat pump as a heat source machine that takes out a heated medium whose temperature is higher than that of a driving heat source. The second type of absorption heat pump has, as its main structure, an evaporator that evaporates the refrigerant liquid, an absorber that absorbs the refrigerant vapor using the absorption liquid, a regenerator that separates the refrigerant from the absorption liquid, and a condenser that condenses the refrigerant vapor. device. The second type of absorption heat pump supplies low-temperature exhausted hot water with relatively low utilization value as a heat source medium to the regenerator and evaporator, thereby being able to take ou...
