Abstract
1,073,776. Heatingand cooling buildings; air conditioning. SULZER BROS. (LONDON) Ltd. July 15, 1964 [July 19, 1963; May 1, 1964], Nos. 28777/63 and 18241/64. Headings F4U and F4V. [Also in Division F2] In an air-conditioning unit a heat exchanger 90 for heating or cooling the air has an inlet which is connectable selectively to a heating fluid supply pipe 86 or to a cooling fluid supply pipe 82 by means of a valve 88 controlled by a thermostat sensitive to local air temperature, and an outlet which is connectable selectively to a heating fluid return pipe 87 or to a cooling fluid return pipe 83 by means of a valve 89 controlled by a thermostat sensitive to the temperature of the fluid leaving the heat exchanger. As shown, the heating and cooling fluid is water circulated by pumps 85, 81 through a heater 84 and a cooler 80. The valves 88, 89 have a lost motion connection between the valve elements and the thermostats so that at a certain air temperature the valve 88 will close both supply pipes, and at a certain temperature of fluid leaving the heat exchanger 90 both return pipes will be open. In this condition the quantity of liquid circulating in each circuit is maintained approximately equal by balance tanks 92, 93 connected to the return pipes so that an increase in the liquid level in one tank, and hence in back pressure is caused by an increase in fluid quantity in either circuit. An overflow connection 94 prevents excessive build-up of back pressure in either circuit and float-operated valves 95 admit make-up water. The air may pass through air filters, humidifiers or de-humidifiers 97, 98, 99 before being blown by a fan 96 over the heat exchanger 90 to be heated or cooled before passing into a room.
