摘要： Provided is an air-conditioning apparatus capable of reducing an amount of refrigerant being used and of preventing a leakage of the refrigerant to a room space. The air-conditioning apparatus includes an outdoor-unit casing accommodating therein a compressor, a refrigerant flow switching device, and a heat-source-side heat exchanger; a heat-medium-relay-unit casing accommodating therein an expansion device and an intermediate heat exchanger; a heat-medium-flow-control-unit casing accommodating therein a heat medium flow control device; an indoor-unit casing accommodating therein a load-side heat exchanger and an indoor air-sending device; and a heat medium conveying device configured to convey a heat medium. In the air-conditioning apparatus, the compressor, the refrigerant flow switching device, the heat-source-side heat exchanger, the expansion device, and a refrigerant passage of the intermediate heat exchanger communicate with each other via refrigerant pipes to form a refrigerant circuit, refrigerant flowing through the refrigerant pipe; and a heat medium passage of the intermediate heat exchanger, the heat medium conveying device, the heat medium flow control device, and the load-side heat exchanger communicate with each other via heat medium pipes to form a heat medium circuit, the heat medium flowing through the heat medium pipe.

摘要： Water cooler (20) comprising: a compressor (1) sending a cooling medium to an evaporative condenser (4) in which condensation heat is subtracted by the air flow sucked by the pipe (14) and let out by the fan (12) through a second pipe (13). Water is sent by the pump (5) to the dispenser (8), which sprays said evapora­tive condenser (4) with said water. The evaporator (10) cools water for air conditioning. The cooler can be equipped - for heating water for sanitary use - with a second condenser (18) arranged in series with the evaporative condenser (4).

摘要： A heating and/or cooling system having a system controller (10) and a number of heating and/or cooling sources (2-1, 2-2, 2-n), which may be multi-stage heat pumps, the heating and/or cooling sources (2-1, 2-2, 2-n) being operated in parallel with respect to the delivery of the heated or cooled working medium. Each of the sources (2-1, 2-2, 2-n) is controlled by an individual controller (5-1, 5-2, 5-n) which is issued with demand signals from the system controller (10). The system controller (10) commands the sources (2-1, 2-2, 2-n) to increase or decrease their heating or cooling capacity by comparing the temperature of mixed working medium from the parallel outlets (6) of the sources (2-1, 2-2, 2-n) to preset reference values. The system controller (10) sequentially energises or de-energises the sources (2-1, 2-2, 2-n) so that at any time the only minimum number of sources (2-1, 2-2, 2-n) which can satisfy the heating and/or cooling demand are energised.

摘要： A ceiling radiant panel device (10) especially one arranged in the upper region of a space to be brought to a certain temperature, with means (14) to which a temperature is applied, especially heating or cooling elements (14) to which a heating or cooling medium can be applied. The temperature being primarily transmitted by radiation from the underside of the ceiling radiant panel device (10) into the temperature-controlled space, is characterized in that there is an air movement producing device (28) beneath and at a distance from the ceiling radiant panel device (10). The invention makes it possible for the prior art transmission of heat by radiation to be enhanced by convection.
