摘要： PROBLEM TO BE SOLVED: To prevent cavitation from being caused in an absorbing solution pump and further prevent abnormal temperature rise and abnormal pressurization in a high temperature regenerator, by preventing internal pressure from being abruptly lowered in an evaporator due to abrupt condensation of high temperature refrigerant and controlling boiling of an absorbing solution, when the indoor unit side of an absorption cooler/heater is rapidly changed to a high load during heating operation.
SOLUTION: Temperature of cold/hot water returning from an indoor terminal device into an evaporator 4 is detected during heating operation by a cold/ hot water return thermistor T as a load change detecting means. A temperature gradient per unit time (ΔT/Δt) is calculated for the temperature of the cold/hot water detected by the thermistor T. If the gradient reaches a specified value, the judgement that the indoor terminal device side is rapidly changed to a high load is made, and heating is suspended until heating by a gas burner B is started. In the case that heating has been started, heating is interrupted. Thus, abrupt condensation of the high temperature vapor is prevented from being caused in the evaporator 4 so that cavitation is prevented from being caused in the absorbing solution pump P1.

摘要翻译：要解决的问题：为了防止在吸收溶液泵中引起气蚀，并且通过防止内部压力由于高温制冷剂的突然冷凝而在蒸发器中突然降低而进一步防止高温再生器中的异常升温和异常加压并且当加热操作期间吸收式冷却器/加热器的室内机侧迅速变为高负载时，控制吸收液的沸腾。解决方案：通过作为负载变化检测装置的冷/热水返回热敏电阻T在加热操作期间检测从室内终端装置返回到蒸发器4的冷/热水的温度。对于由热敏电阻T检测出的冷/热水的温度，计算出每单位时间的温度梯度（ΔT/Δt）。如果梯度达到规定值，则室内终端装置侧迅速变为高进行负载，并且停止加热直到燃气燃烧器B的加热开始。在加热开始的情况下，加热中断。因此，防止在蒸发器4中引起高温蒸汽的突然冷凝，从而防止在吸收液泵P1中引起空化。

摘要： PROBLEM TO BE SOLVED: To prevent the supercooling of an evaporator and eliminate the trouble in cooling operation, when a load from the side of an indoor terminal machine is very small upon cooling operation and cooling operation stopping process or the like during the cooling operation, or when cold start is effected under a condition that a feed water temperature is low, in an absorptive cooling and heating machine.
SOLUTION: The temperature of the evaporator 4 is detected by a first thermistor Tf upon cooling operation and cooling operation stopping process or the like during the cooling operation. The temperature of the evaporator 4 is judged based on an output from the first thermistor Tf whether the same is lower than 3°C or not. When the temperature is lower than 3°C, both or either one of a cooling tower fan S or a cooling water pump P2 is stopped. When the temperature of the evaporator 4 is raised to a value higher than 7°C, the operation of both or either one of the cooling tower fan S or the cooling water pump P2 is re-started. According to this method, the supercooling and freezing of the evaporator 4 is prevented whereby the cooling operation is continued without interruption.
