摘要： PURPOSE: To improve the responsiveness of a temperature control in a refrigerant circulation type air-conditioning system. CONSTITUTION: In an air-conditioning system wherein a refrigerant condensed in an outdoor machine 1 is sent to a plurality of indoor machines 2, evaporated in each indoor machine 2 and returned to the outdoor machine 1, while the degree of opening of an expansion valve 4 interposed in a branch refrigerant piping on the upstream side of each indoor machine 2 is controlled so that a temperature difference, (Tb-Ta) of the refrigerant between the outlet and the inlet of each indoor machine 2 be a prescribed value, a means for changing over a control target value of the temperature difference in a plurality of stages in accordance with a temperature or a pressure detected by a refrigerant temperature sensor 12 or a refrigerant pressure sensor provided at the outlet of the outdoor machine 1 is provided. Since the degree of overheat being a control target of the expansion valve 4 is changed over simultaneously when a load of the outdoor machine 1 changes suddenly, accordingly, the temperature difference of the refrigerant at that time point deviates to a large extent from the control target value (target degree of overheat). Accordingly, the degree of opening of the expansion valve 4 is modified immediately and sharply and thus it can cope with the sudden change of the load of the outdoor machine 1.

摘要： PROBLEM TO BE SOLVED: To prevent a stopping of circulation of refrigerant without using any liquid receiver against a fast reduction in load at an indoor device in an air conditioning system in which refrigerant is automatically circulated. SOLUTION: A plurality of air conditioning devices 1 are installed at an area to be air conditioned and an absorbing-type freezer 2 is arranged at a higher location than the air conditioning devices 1. A radiator 8 in an evaporator 7 of the absorbing type freezer and a heat exchanger 3 in each of the air conditioning devices are connected by a refrigerant liquid pipe 10 and a refrigerant gas pipe 11 so as to form a refrigerant circuit, wherein the refrigerant gas is condensed in the radiator 8 and refrigerant liquid is evaporated in the heat exchanger 3 to cause the refrigerant to be automatically circulated in the circuit. A differential pressure sensor 12 for use in sensing a pressure difference between the insides of both pipes near each of their lower ends is arranged between the refrigerant liquid pipe and the refrigerant gas pipe. This sensor 12 temporarily stops an operation of the absorbing type freezer as a lower pressure differential value than a predetermined set value and after elapsing a certain period of time, the operation is started again.

摘要： PROBLEM TO BE SOLVED: To enhance the heat transmission performance of an evaporating tube and improve the dynamic behavior of an apparatus where an evaporator is used by a groove-shaped section extended in the longitudinal direction of an evaporating tube on the lower side of the evaporating tube. SOLUTION: Since the flow of a liquid of an evaporating tube 1 is the flow of an open channel, the free surface of the liquid is a surface having a slope falling obliquely from an inlet S1 to an outlet surface S3 by way of an intermediate surface S2 . As a slit 12 is provided below a spring 11, the liquid can pass in the slit 12 below the souring so that there may be no need for the fluid to flow across the spring 11. As a result, the free surface may be formed in the range of a linear diameter of the spring 11. With the flow of the liquid as described above, any are a which many become not only a surface evaporation heating transfer surface but also a convection heat transfer surface having a low heat transfer rate, is the maximum in the inlet of the fluid and lead to A position from the bottom of the tube and may become substantially O in the outlet of the liquid.

摘要： PROBLEM TO BE SOLVED: To lessen the area of installation and to reduce the quantity of holding liquid. SOLUTION: A high temperature regenerator as steam generating equipment has an outer tube 1, an inner tube 2, a passage 3, a vapor-liquid separating part 9, etc. The inner tube 2 has a lower part 2a constructed of a straight tube forming a combustion chamber 4, an upper part 2b constructed of a bellows tube, etc. An absorbent liquid which absorbs a refrigerant is made to flow through the passage 3. Accordingly, the lower part forming a radiation heat transfer surface and the upper part forming a contact heat transfer surface are provided upright in a straight line and, therefore, an installation space is minimized. Since a space between the inner and outer tubes is made the liquid passage, the holding amount of liquid is reduced and the equipment cost is also reduced. Heat exchange is facilitated in the part of the bellows tube and a necessary amount of evaporation is ensured.

CONSTITUTION: A temperature sensor 11a detects the temperature of a low- temperature dilute solution sent to a regenerator 1 through a solution heat exchanger 5. A temperature sensor 11b detects the temperature of a returning high-temperature concentrated solution coming out from the regenerator 1. A valve 12 regulates the quantity of refrigerant sent from a refrigerant storage chamber 6 to an evaporator 4. A control box 13 is a control device which receives detection signals from the temperature sensors 11a and 11b and others as inputs and controls the opening of the valve 12 in accordance with those detection signals. Accordingly, the quantity of heat input in the regenerator can be controlled simply relatively.
