摘要： An air conditioning system comprises a heat source side unit adapted to condense and supply a fluid which can change a phase between a gas phase and a liquid phase and a plurality of user side units entirely or mostly disposed below the heat source side unit in terms of number and connected to said heat source side unit by piping so as to establish a circulation of the fluid supplied from said heat source side unit passing through said heat source side unit and said user side units by utilizing the difference in specific gravity between the liquid phase and the gas phase of said liquid so that it can provide a cooling/heating effect regardless of the floors where the user side units are installed and the power consumption rate of the system can be minimized. More specifically, the heat source side unit 1 and the user side units 4 arranged below the heat source side unit 1 are connected by way of liquid phase piping 6 and gas phase piping 7 to form a closed circuit 3 and a motor pump 10 is arranged along the liquid phase piping 6. Refrigerant R-134a is condensed in the heat source side unit 1 and sent to the user side units 4 by the motor pump 10 in the cooling mode of operation, whereas it is condensed in the user side units 4 and sent to the heat source side unit 1 by the motor pump 10 in the heating mode of operation. The number of revolutions per unit time of the motor pump is controlled modifying the number of poles of the pump or the frequency of the AC fed to the pump.

摘要： An air conditioning system comprises a heat source side machine such as an absorption type refrigerator, a plurality of user side machines more than half of which are disposed below the heat source side machine, and liquid phase and gas phase pipes connecting the heat source side machine with the user side machines to form a closed circuit. A phase-changeable fluid circulates between the heat source side machine and the user side machines by utilizing its own specific gravity difference between the liquid and gas phases and a driving force of an electric pump provided to the liquid phase pipe, so that each of the user side machines can perform cooling operation. A receiver tank is provided to the inlet side of the electric pump, and an upper portion of the receiver tank is connected to the gas phase pipe by a pressure-equalizing pipe so as to improve a start characteristic of the cooling operation. Moreover, the fluid transported from the electric pump is recooled in the heat source side machine so that the fluid heated by the electric pump does not generate bubbles in the liquid phase pipe when being transported to the user side machine that performs cooling operation.

摘要： An air conditioning system comprises a heat source side machine, a plurality of user side machines more than half of which are disposed below the heat source side machine, and liquid phase and gas phase pipes connecting the heat source side machine with the user side machines to form a closed circuit. A phase-changeable fluid included in the closed circuit circulates by utilizing its own specific gravity difference between the liquid and gas phases, so that each of the user side machines can perform cooling and heating operations. The liquid phase pipe and the gas phase pipe can communicate with each other via a gas bypass circuit and/or a liquid bypass circuit including a open-close valve and liquid level detection means, so that bubbles or condensed liquid generated in the closed circuit can be exhausted quickly.

摘要： An absorption refrigerating machines-group apparatus that can be installed at reduced cost and prevent the occurrence of abnormal situations due to the unexpected suspension of the operation of a cooling water pump is provided. The absorption refrigerating machines-group apparatus according to the invention comprises a control panel 200 for issuing control signals, an adapter 300 having a control section 310 for relaying control signals and absorption refrigerating machines 100A, 100B, 100C having respective control sections 80, said control sections 310 and 80 being connected by a telecommunications line L51. When a signal for suspending the operation of the shared cooling water pump is relayed, the currently operating absorption refrigerating machines are brought into a temporary state that allows the operation of the cooling water pump P2 to be suspended through an exchange of signals between the control sections 310 and 80. After obtaining a "pump suspension signal" from each and every one of the absorption refrigerating machines, the control section 310 suspends the operation of the cooling water pump P2. The control section 310 can also suspend the operation of the cooling water pump P2 by seeing the signal representing the operation of the value-setting section 330 and determining if the pump sharing arrangement or the individual pump arrangement is currently selected.
