摘要： PURPOSE:To improve a regulating accuracy of coolant concentration irrespective of variations in an operating state, a coolant temperature, etc., by so regulating a flow rate of refrigerant liquid that a concentration of absorption liquid becomes a target value set in response to a temperature of the coolant. CONSTITUTION:Concentration calculating means 31 calculates a concentration of absorption liquid from a detected temperature of coolant temperature detecting means Sw and a detected temperature of absorption liquid temperature detecting means Sy based on correlation among the concentration, the temperature of the liquid, and a temperature of coolant. Since absorption capacity of the liquid is different according to the temperature of the coolant, it is necessary to regulate the concentration of the liquid to a suitable concentration responsive to the temperature of the coolant. Then, target concentration setting means 32 sets a suitable target concentration responsive to the detected temperature of the means Sw. Flowrate control means 33, 34 operate to bring the calculated concentration of the means 31 to the target concentration. Thus, a regulating accuracy of the concentration of the liquid can be improved irrespective of variations in an operating state, the temperature of the coolant, etc.

摘要： PURPOSE:To dissolve conventional problems, such as lowering of freezing capacity owing to absorption capacity of absorption liquid wherein a using amount of a surfactant is high, by a method wherein concentration of a surfactant in the absorption liquid is maintained at a proper value. CONSTITUTION:In an absorption type freezer comprising a vaporizer 6 to vaporize a refrigerant; and an absorber 5 to absorb refrigerant steam vaporized by the vaporizer 6 in surfactant-containing absorption liquid, a surfactant is fed in a steam state along with lowering of a steam pressure so that a steam pressure of surfactant in the absorber 5 attains a saturated steam pressure. A feed means K to stop a feed with the increase of the steam pressure to the saturated steam pressure is provided. The feed means K stores the surfactant in a state to prevent invasion of absorption liquid and comprises a container 31 arranged in the absorber 5; and a communicating part 32 to intercommunicate the interior of the container 31 and the interior of the absorber 5.

摘要： PROBLEM TO BE SOLVED: To solve the problem of a usual indiscriminate diluting operation for a cooling operation conducted after recovery of power when the cooling operation is executed on the occasion of a power failure, considering that there are various cases in the state of the operation at the power failure and therefore the indiscriminate dilution causes waste.
SOLUTION: When power recovers in the case of the power failure in the course of the cooling operation, a means for the diluting operation mounted on a controller executes a simple diluting operation when the temperature of a high-temperature regenerator 15 which is stored at the power failure is below 60°C. When this temperature is 60°C or above, simulated cooling is executed according to the condition and the diluting operation is conducted. A useless diluting operation is held down consequently and crystallization can surely be prevented. Since the dilution is conducted by executing the simulated cooling operation according to the condition, an absorbing solution in an absorption type refrigerating cycle 7 can be circulated efficiently and, as the result, a dilution time can be shortened.

摘要： PROBLEM TO BE SOLVED: To solve the problem that, even when trial cooling operation is instructed to the conventional heating-cooling combination appliance, the appliance suspends the trial cooling operation when a refrigerant has a possibility of being frozen in an absorption refrigerating cycle and, though the actuation check of the refrigerating cycle can be complemented by trial heating operation, the confirmation of the operation of the appliance is not possible, because a cooling tower and a water feeding means which automatically replenishes the tower with cooling water are not used at the time trial heating operation. SOLUTION: In the case that trial cooling operation is instructed, the trial operations of the cooling tower 4 and water feeding means 65 are performed when the cooling water has no possibility of being frozen in the tower 4 and means 65 (the outside temperature is >=3 deg.C) even when the refrigerant has a possibility of being frozen in the absorption refrigerating cycle 7 (outside temperature is

摘要： PROBLEM TO BE SOLVED: To make a decision easily whether an abnormal state is present in a heat exchanger or not by providing a pair of conduction stopping means, respectively, on the upstream side and downstream side of a heat exchanger in a hot water conduction channel and making a decision whether a detected pressure is higher than a set level or not based on pressure detection information under a state where conduction of hot water is stopped. SOLUTION: A hot water supply controller TC controls a circulation pump 3, a combustor N, three-way valves 7b, 8b, 9b, and an on/off valve V based on a command from a hot water supply operating unit KS and performs hot water supply operation. If a minimum necessary hot water is not stored in a hot water storage tank at the execution timing of hot water supply operation, hot water storage operation is performed. Every time when a set time elapses, a pair of on/off valves are switched to conduction stop state and a decision is made whether a detected pressure is higher than a set level or not based on information detected through a pressure sensor P. If a detected pressure is higher than the set level, a decision is made that a heat exchanger is abnormal and hot water supply operation is stopped.
