Refrigeration system having dual suction port compressor

摘要

A cooling system for appliances, air conditioners, and other spaces includes a compressor, and a condenser that receives refrigerant from the compressor. The system also includes an evaporator that receives refrigerant from the condenser. Refrigerant received from the condenser flows through an upstream portion of the evaporator. A first portion of the refrigerant flows to the compressor without passing through a downstream portion of the evaporator, and a second portion of the refrigerant from the upstream portion of the condenser flows through the downstream portion of the evaporator after passing through the upstream portion of the evaporator. The second portion of the refrigerant flows to the compressor after passing through the downstream portion of the evaporator. The refrigeration system may be configured to cool an appliance such as a refrigerator and/or freezer, or it may be utilized in air conditioners for buildings, motor vehicles, or other such spaces.

主权项

1. An appliance cooling system configured so as to cool an insulated interior space of an appliance, the appliance cooling system comprising:
a compressor; a condenser that receives refrigerant flowing from the compressor; an evaporator that receives refrigerant flowing from the condenser, the evaporator defining upstream and downstream portions, and wherein refrigerant received from the condenser flows through the upstream portion of the evaporator, a first portion of the refrigerant flowing to the compressor without passing through the downstream portion of the evaporator, a second portion of the refrigerant from the upstream portion flowing through the downstream portion of the evaporator after passing through the upstream portion of the evaporator, the second portion of the refrigerant flowing to the compressor after passing through the downstream portion of the evaporator; a refrigerant expander operably coupled to the condenser and the evaporator and permitting expansion of refrigerant flowing from the condenser to the evaporator; and a structure rigidly interconnecting the upstream and downstream portions of the evaporator so that the evaporator can be moved as a unit and mounted to a refrigeration unit of the type that has an insulated interior space.
