A corrosion inhibitor module for a packaged terminal air conditioner unit (PTAC) is provided. Condensate is pumped from a drain pan of the PTAC into a housing of the corrosion inhibitor module. The housing contains a corrosion inhibitor concentrate that is mixes with the condensate to form an inhibitor solution that is returned to the drain pan to prevent the corrosion of components that come in contact with the condensate.

An air-conditioner having a compressor, a condenser and an evaporator. The air-conditioner further includes a liquid-to-suction heat exchanger provided in a flowpath from the condenser to the evaporator.

Disclosed are a refrigeration module capable of reducing a temperature of a storage room within a short time and a bathroom management apparatus including the same. A refrigeration module may include an outer case, a thermoelectric module, a first heat sink provided on a first surface of the thermoelectric module to produce heat and second heat sink provided on a second surface of the thermoelectric module to absorb heat, and a blowing fan.

A bathroom management apparatus includes: a cabinet having an open front; at least one frame configured to be installed at an inner side of the cabinet; at least one function module, wherein the at least one function module is one of a towel care module, a sterilizing module, a secret box module, a refrigerating module, a charging module, and an air conditioning module configured to be installed inside the at least one frame body, wherein guide ribs are formed at both sides of the at least one function module, and inner ribs are formed at first and second side frames of the frame, and are configured to guide and support the guide ribs when inserting the at least one function module into the at least one frame.

Disclosed is a bathroom management apparatus having a storage space for various function modules, and capable of dividing the storage space into various sizes. The bathroom management apparatus may include a cabinet, a frame installed in the cabinet to reinforce stiffness of the cabinet; and a function module may include a towel care module. The function module includes an outer case configured to provide a storage space, a back plate provided inside the outer case to form a rear surface of the storage space, and an attachment groove being formed at a front surface at the back plate, a metal plate disposed at a rear surface of the back plate, and a partition removably coupled to the front surface of the back plate to divide the storage space. The partition may include an attachment protrusion configured for insertion into the attachment groove and a magnet coupled to the metal plate.

Portable air conditioner provided with an external container comprising internally a refrigerating circuit provided with a condenser.

An air conditioning tower includes a tower casing, a compressor provided in the tower casing, a heat exchanger provided in the tower casing and connected to the compressor, an evaporative cooling system which includes at least one multiple-effect evaporative condenser, and a centrifugal fan. The multiple-effect evaporative condenser includes a pumping device, a first cooling unit, a second cooling unit, and a bottom water collecting basin. The first cooling unit includes a first water collection basin, a plurality of first heat exchanging pipes, and a first fill material unit. The second cooling unit includes a second water collection basin, a plurality of second heat exchanging pipes, and a second fill material unit.

A packaged terminal air conditioner unit (PTAC) and methods of operating the same are provided. The PTAC includes a bulkhead having a vent aperture through which an auxiliary fan urges a flow of make-up air into the room and a vent door for controlling the flow of make-up air. A method for detecting the position of the vent door includes operating the auxiliary fan at a first power level to reach a target speed, switching the position of the vent door, and operating the auxiliary fan at a second power level to maintain the target speed. The first power level and the second power level are compared to determine whether the vent door is in the open position or the closed position, with an increased power level indicating that the door is closed and a decreased power level indicating that the door is open.
