BAROCALORIC HEATING AND REFRIGERATOR SYSTEM IN CLOSED CYCLE, CONTROL PROCEDURES FOR SUCH SYSTEM, AND CONTROLLERS AND COMPUTER PROGRAMS TO CARRY OUT SUCH CONTROL PROCEDURES (MACHINE-TRANSLATION BY GOOGLE TRANSLATE, NOT LEGALLY BINDING)

Closed cycle barocaloric heating and cooling system, control procedures for said system, and controllers and computer programs to carry out said control procedures. Heating and cooling systems are provided that comprise a fluidic circuit, a pressure unit, and operating units that include a first and a second active barocaloric exchangers, a heater bulb and a cooler bulb. The fluidic circuit causes a heat transfer fluid to circulate between and through the operating units. Each exchanger houses barocaloric material so that the heat transfer fluid absorbs heat from the barocaloric material under pressurization or yields heat to the barocaloric material under depressurization. The unit of pressure produces the pressurization and depressurization. The heating bulb causes the heat transfer fluid, which has absorbed heat in one of the exchangers, to circulate, heating its surroundings. The cooling bulb makes the heat transfer fluid, which has given up heat in one of the exchangers, to circulate, cooling its surroundings. Also provided are procedures for the control of such heating and cooling systems, and suitable drivers and computer programs to perform such procedures.
