Abstract
A heating, ventilation, and/or air conditioning (HVAC) system includes a vessel configured to receive refrigerant from a condenser of the HVAC system, an evaporator configured to receive the refrigerant from the vessel, a first conduit configured to direct a first flow of the refrigerant to a first inlet of the evaporator, and a second conduit configured to direct a second flow of the refrigerant to a second inlet of the evaporator. The second inlet is above the first inlet relative to a vertical axis.
Claims18
A heating, ventilation, and/or air conditioning (HVAC) system, comprising:
- a vessel configured to receive refrigerant from a condenser of the HVAC system;
- an evaporator configured to receive the refrigerant from the vessel;
- a first conduit configured to direct a first flow of the refrigerant to a first inlet of the evaporator, wherein the first inlet is disposed at a bottom section of the evaporator;
- and
- a second conduit configured to direct a second flow of the refrigerant to a second inlet of the evaporator, wherein the second inlet is above the first inlet relative to a vertical axis.
A heating, ventilation, and/or air conditioning (HVAC) system, comprising:
- a vessel configured to receive refrigerant from a condenser and to separate the refrigerant received from the condenser into vapor refrigerant and liquid refrigerant;
- a first conduit configured to direct a first flow of liquid refrigerant to a first inlet of an evaporator of the HVAC system, wherein the first conduit comprises a bypass valve, and the first inlet is disposed at a bottom section of the evaporator;
- a second conduit configured to direct a second flow of liquid refrigerant to a second inlet of the evaporator, wherein the second inlet is above the first inlet relative to a vertical axis;
- and
- a controller communicatively coupled to the bypass valve, wherein the controller is configured to operate the bypass valve to control a flow rate of the first flow of liquid refrigerant to the evaporator via the first conduit.
A heating, ventilation, and/or air conditioning (HVAC) system, comprising:
- a condenser;
- an intermediate vessel configured to receive refrigerant from the condenser;
- an evaporator configured to receive the refrigerant from the intermediate vessel;
- a first conduit extending between the condenser and the intermediate vessel, wherein the first conduit comprises an expansion valve configured to reduce a pressure of the refrigerant directed through the first conduit to enable separation of the refrigerant into liquid refrigerant and vapor refrigerant within the intermediate vessel;
- a second conduit extending between the intermediate vessel and a first inlet of the evaporator, wherein the second conduit is configured to direct the liquid refrigerant into the evaporator via the first inlet, and the first inlet is disposed at a bottom section of the evaporator;
- and
- a third conduit extending between the intermediate vessel and a second inlet of the evaporator, wherein the second inlet is above the first inlet relative to a vertical axis, and the third conduit is configured to direct the liquid refrigerant into the evaporator via the second inlet.
