<p>The refrigeration installation with reduced hysterisis consists of a refrigerating fluid compressor (1), a codenser (2), a lamination valve (8) and an evaporator (10,22) for exchanging heat with the refrigerated fluid; it has an injection line (3) of hot gases taken downstream of the compressor (1) and injected upstream of the evaporator (10); it has at least one injection command and control electrovalve (9); it also has a second interception electrovalve (7) placed upstream of the lamination valve (8); this second electrovalve (7) is activated in phase inversion in relation to injection command and control electrovalve (9); it also has a probe (21,26) for indicating the temperature of the refrigerated fluid at the exit of the evaporator (10,22), the probe being situated in proximity thereto. <IMAGE></p> |
