Problems solved by technology
In such a situation, if the liquid level detection sensor detects the upper limit or lower limit of the specified range, immediately perform the control of reducing or increasing the frequency of the frequency converter by a certain amount, so that the solution sent from the absorber to the high temperature regenerator If the flow rate decreases or increases, the frequency of the change due to the operating frequency before the change will be too large or too small, resulting in unstable liquid level control

The invention provides an absorption-type heat source device, and the device can carry out stable level control in a full-load zone. Through the circulation of refrigerant and solution, the device is provided with object forming equipment of a liquid storage part for temporarily storing object liquid during the period from a moment when the object liquid is guided into the object forming equipment to a moment when the object liquid is guided out. The device is also provided with a liquid pump which can employ a frequency converter to adjust the outflow rate of the object liquid; an internal pressure detector; a liquid level detector which is used for detecting the deviation of the storage level of the object liquid in the liquid storage part from a standard liquid level; and a control device which transmits a flow adjustment signal to the frequency converter. When the storage level is at the standard liquid level, the control device enables a standard frequency corresponding to an internal pressure to serve as an operation frequency for transmission. When the storage level deviates from the standard liquid level, a detection correction frequency value is increased or decreased and serves as a new operation frequency for transmission. The detection correction frequency value is a first specified proportional value of the standard frequency during deviation.
Description
technical field [0001] The present invention relates to an absorption heat source device, in particular to an absorption heat source device capable of stable liquid level control in a full load region. Background technique [0002] An absorption refrigerating machine, one of absorption heat source devices, includes a regenerator that introduces a dilute solution and heats it to evaporate the refrigerant to generate a concentrated solution, a condenser that condenses the refrigerant vapor, and a condenser that condenses the condensed refrigerant vapor. An evaporator that evaporates the liquid, and an absorber that absorbs the evaporated refrigerant with a concentrated solution. For the flow of the solution in the absorption refrigerator, the amount of solution returned from the regenerator to the absorber is driven by the position head determined by the configuration of the two and the difference between the pressure of the regenerator and the pressure of the absorber. Etc. ...
