    摘要: Heat exchanger has a first surface on which a first fluid flows and a second surface on which a second fluid flows, at least one of the first and second surfaces has at least two projections and a bottom therebetween, and an imaginary line on the bottom along a shortest distance between the projections adjacent to each other is prevented from extending along an imaginary face substantially parallel to a main flow direction of one of the first and second fluids which flows over the bottom.

    摘要: An unit-type air conditioning system is provided to enable low-load operation of an absorption chiller heater, to thereby improve the load responsiveness, and to use such a chiller heater as an outdoor unit. A plurality of burners are provided in a high temperature generator of the absorption chiller heater, thereby enabling the low-load operation. A refrigerant return valve is provided so as to speed up the stop operation. Flow rates of pumps are controlled in accordance with detected values of temperatures in the chiller heater and a load change, thus improving the load responsiveness. Further, in the air conditioning system with this chiller heater serving as an outdoor unit, required operation prediction is performed on the basis of outer signals from load units and the like, and prediction control according to its result is conducted, further improving the load responsiveness.

    摘要: In an absorption air-conditioning system, in order to immediately stop indoor air-conditions by a stop signal of the indoor air-conditioners and improve characteristics for activating the system , such as, by effecting re-activation at a relatively short time interval after stopping the operation of the system, when the last one of the operating indoor air-conditioners is stopped, a stop signal is sent to a control device from a controller for the indoor air-conditioner, and in response to this signal, the control device effects the control of stopping a burner, a cooling medium circulating pump, a cooling water pump and a cold/hot water, pump. A solution circulating pump, however, continues operating and the solution, while kept at a high concentration, is circulated through an absorber, a high-temperature regenerator and a low-temperature regenerator. During this time, an indicated value of a temperature sensor gradually decreases, and when this value reaches a predetermined temperature, the control device switches a control valve from its open condition to its closed condition and another control valve from its closed condition to its open condition, and also activates the cooling medium circulating pump again to feed a cooling medium to a solution reservoir at a lower portion of the absorber, thereby diluting the solution.

    摘要: An absorber comprises a vapor absorption portion including at least two flow paths through which an absorption solution flows down and absorbs a cooling medium vapor, at least two solution cooling portions separated from, and juxtaposed with, the vapor absorption portion and solution circulation for circulating a cooling medium vapor between the solution cooling portion and the vapor absorption portion. In this manner, a refrigerator can be made compact in size and cycle efficiency can be improved.
