Abstract

L'INVENTION CONCERNE UN SYSTEME DE POMPE A CHALEUR A SOURCE D'AIR. UN COMPRESSEUR ALTERNATIF MULTICYLINDRES PASSE AUTOMATIQUEMENT A UN FONCTIONNEMENT A PLUSIEURS ETAGES DE COMPRESSION LORSQUE LA TEMPERATURE AMBIANTE EST BASSE AFIN D'AMELIORER LE DEBIT DU REFRIGERANT TOUT EN FACILITANT LE FONCTIONNEMENT D'UN SOUS-REFROIDISSEUR ET LE RETOUR DU REFRIGERANT VAPORISE DU SOUS-REFROIDISSEUR A L'ENTREE DES CYLINDRES FONCTIONNANT EN SECOND ETAGE DU COMPRESSEUR DANS LE CYCLE A DEUX ETAGES. PENDANT CE CYCLE A DEUX ETAGES, LES TOURILLONS DES TETES DE PISTON DES CYLINDRES, COTE BASSE PRESSION ET DU CYLINDRE, COTE HAUTE PRESSION, SUBISSENT DES INVERSIONS DE CHARGE CONVENABLES PUISQUE LA PRESSION D'ASPIRATION INTERMEDIAIRE EST APPLIQUEE AU TOURILLON DU PISTON DES CYLINDRES HAUTE PRESSION. APPLICATION AU CHAUFFAGE DES IMMEUBLES.THE INVENTION RELATES TO AN AIR-SOURCED HEAT PUMP SYSTEM. A MULTI-CYLINDER ALTERNATIVE COMPRESSOR SWITCHES AUTOMATICALLY TO MULTI-STAGE COMPRESSION OPERATION WHEN THE AMBIENT TEMPERATURE IS LOW IN ORDER TO IMPROVE THE REFRIGERANT FLOW WHILE FACILITATING THE OPERATION OF A SUB-COOLER AND THE COOLER SUB-COOLER THE ENTRY OF THE CYLINDERS OPERATING AS A SECOND STAGE OF THE COMPRESSOR INTO THE TWO STAGE CYCLE. DURING THIS TWO-STAGE CYCLE, THE PISTON HEADS OF THE CYLINDERS, LOW PRESSURE SIDE AND OF THE CYLINDER, HIGH PRESSURE SIDE, SUBJECT SUITABLE LOAD REVERSIONS SINCE THE INTERMEDIATE SUCTION PRESSURE IS APPLIED TO THE PRESSURE PISTON CYLINDER. . APPLICATION TO THE HEATING OF BUILDINGS.
