An air conditioner indoor unit includes an air outlet frame, a front water receiving tray, and a panel. The air outlet frame includes an upper enclosure plate, a lower enclosure plate, and a side enclosure plate located between and connecting the upper enclosure plate and the lower enclosure plate. The front water receiving tray is above the upper enclosure plate and includes a protrusion section protruding out of the side enclosure plate and a water outlet hose at the protrusion section. The water outlet hose is configured to be received in a receiving cavity formed below the protrusion section and opening forward. The panel includes a cover member configured to cover the receiving cavity when the panel is in a closed state.

There is presented a heating, ventilation and air conditioning (HVAC) system for conditioning air within a chamber, the system comprising: an inlet, an outlet, and a conditioning unit, the conditioning unit comprising a fan, and a heat exchanger configured to exchange heat with the air within the conditioning unit, wherein during operation, air is urged through conditioning unit by the fan such that heat is exchanged between the air and the heat exchanger, wherein the fan is configured to vary the flow rate of air urged through the conditioning unit to thereby control the amount of heat transferred between the air and the heat exchanger.

Methods and related systems of detecting a temperature deviation in a heat exchanger coil of a climate control system. The method includes determining an enthalpy of the indoor space. The method includes detecting a coil temperature of the heat exchanger. The method includes detecting a coil temperature deviation based on the enthalpy and the detected coil temperature.

An air conditioner indoor unit includes a chassis, an air duct assembly detachably connected with the chassis, a face frame including a detachment opening configured to allow the air duct assembly to pass through, a first panel configured to open or close the detachment opening, and a second panel configured to cooperate with the first panel to cover a surface of the face frame.

An antistatic structure includes a casing, an element disposed in the casing, and a first conductive member disposed on an inner face of the casing and configured to send static electricity to a ground. The first conductive member is at least partially disposed around a region opposite the element in the casing.

An air duct device and an air handling apparatus are provided. The air duct device can include a housing, a first air duct, and a second air duct. The first air duct is arranged in the housing and has an air input end and an air output end. The second air duct is arranged in the housing and has an air input end and an air output end. The air input end of the second air duct passes by the air output end of the first air duct.

A refrigeration or climate-control system may include a housing, an evaporator, a drain pan, and a fan. The evaporator may be disposed within the housing and may include a coil positioned in a horizontal orientation. The drain pan may be disposed within the housing and may include an inclined lower wall disposed vertically beneath the coil. The lower wall may define an airflow path underneath the coil. The fan may force the air through the housing and airflow path.

Apparatuses, systems, methods, and computer program products for an electric fireplace are described. An apparatus may include an electronic display configured to display one or more flame visualizations. An apparatus may include a heat source coupled to the electronic display and configured to heat a surrounding environment. An apparatus may include a cooling source coupled to the electronic display and configured to cool the surrounding environment, the electronic display, the heat source, and the cooling source sharing a single power source.

A cooling system includes a cooling device having a first cooling coil and a second cooling coil, a first heat transfer fluid in fluid communication with the first cooling coil, a second heat transfer fluid in fluid communication with the second cooling coil, a first heat exchanger in fluid communication with the first heat transfer fluid and the second heat transfer fluid, a second heat exchanger in fluid communication with the second heat transfer fluid and a source of external air, a system of fluid control devices in fluid communication with the second heat transfer fluid and configured to minimize a change in a total pressure drop of the second heat transfer fluid when the cooling system switches between operating modes, and a controller configured to selectively control the cooling device and the system of fluid control devices to operate the cooling system in each of the operating modes.

An air conditioner is provided. A main body of the air conditioner is provided with an air outlet facing a front lower side of the main body. An upper passage is arranged above the air outlet and in communication with the air outlet, and is adapted to supply air forwardly. An upper air deflection assembly is used to direct air to flow out of a terminus of the upper passage. The upper air deflection assembly has an upper air diffusing plate. A front air deflection assembly is used to direct air to flow out of a terminus of the air outlet.
