An evaporative condenser for use in a refrigeration or air-conditioning system includes one or more condensing coils arranged in a condensing coil zone. The coils condense therewithin a refrigerant of the system. The condenser also includes a mechanism for wetting the one or more condensing coils. The condenser further includes drift eliminators arranged to remove free water from an airstream A that has flowed past the one or more condensing coils and wetting mechanism. The condenser additionally includes a divergent zone that diverges from the condensing coil zone towards the drift eliminators such that, once the airstream has flowed past the one or more condensing coils, it flows into and through the divergent zone to the drift eliminators.

Embodiments of a spill over tank for an evaporator of a HVAC system are described. The spill over tank may be configured to receive a refrigerant directed out of the evaporator. The spill over tank may be configured to have an outlet directing refrigerant in the spill over tank out of the spill over tank and flowing back to a compressor of the HVAC system. The spill over tank may be equipped with a refrigerant level sensor configured to measure a refrigerant level in the spill over tank. The measured refrigerant level in the spill over tank may be used to control and/or maintain a refrigerant level in the evaporator, and/or may be used to control a return refrigerant flow into the compressor of the HVAC system so as to manage an oil return to the compressor.

A condenser vessel having an oil storage and separation portion for separating a refrigerant vapor from oil in a temperature conditioning system includes a casing and a separator wall positioned inside the casing. The casing includes an inlet for receiving a mixture of oil and refrigerant vapor and an outlet for transferring the oil separated from the mixture of the oil and the refrigerant vapor outside the condenser vessel. The separator wall is positioned inside the casing along a lateral axis (A-A) of the casing substantially perpendicular relative to a horizontal axis (X-X) through a centre of the casing. The separator wall defines a condenser portion and an oil storage and separation portion within the casing.

Systems and methods for natural gas liquefaction capacity augmentation using supplemental cooling systems and methods to improve the efficiency of a liquefaction cycle for producing liquefied natural gas (LNG).

A multi-step method is disclosed for exchanging heat in a vapor compression heat transfer system having a working fluid circulating therethrough. The method includes the step of circulating a working fluid comprising a fluoroolefin to an inlet of a first tube of an internal heat exchanger, through the internal heat exchanger and to an outlet thereof. Also disclosed are vapor compression heat transfer systems for exchanging heat. The systems include an evaporator, a compressor, a dual-row condenser and an intermediate heat exchanger having a first tube and a second tube. A disclosed system involves a dual-row condenser connected to the first and second intermediate heat exchanger tubes. Another disclosed system involves a dual-row evaporator connected to the first and second intermediate heat exchanger tubes.
