Abstract: A flash gas bypass system includes a separation assembly having an inlet configured to receive a refrigerant flow from an expansion valve. A bypass conduit is coupled to a first port of the separation assembly and configured to receive a first portion of the refrigerant flow via the first port, where the first portion of the refrigerant flow includes flash gas. A second port of the separation assembly is coupled to an outlet conduit in fluid communication with an evaporator. The outlet conduit is configured to receive the second portion of the refrigerant flow via the second port and direct the second portion of the refrigerant flow toward the evaporator, where the second portion of the refrigerant flow includes liquid refrigerant. A filter is configured to redirect droplets captured by the filter from the first portion of the refrigerant flow into the second portion of the refrigerant flow.

Abstract: A heating, ventilation, and/or air conditioning (HVAC) system, includes a housing having a wall with an exterior surface configured to be exposed to an ambient environment. The HVAC system further includes a first heat exchanger disposed within the housing and forming part of a refrigerant circuit of the HVAC system and a second heat exchanger disposed within the housing and forming part of the refrigerant circuit, in which the second heat exchanger includes a coil coupled to the wall, such that the coil and the wall are configured to transfer heat between the ambient environment and refrigerant passing through the second heat exchanger.

Abstract: Embodiments of the present disclosure include a drive belt tensioner configured to adjust tension in a drive belt of a blower assembly for a heating, ventilation, and/or air conditioning (HVAC) system. The drive belt tensioner includes a mounting bracket configured to couple directly to a blower housing that is configured to house a blower of the blower assembly. The drive belt tensioner further includes an idler pulley configured to contact the drive belt. A position of the idler pulley is adjustable relative to the mounting bracket to enable adjustment of the tension in the drive belt.
