An interior mounted condenser for temperature control in a building has a condenser housing with an inlet opening facing into the building interior, an outlet opening communicating with an exterior outlet through an exterior wall of the building. A condenser coil and a fan are disposed in the housing. The condenser also has a plenum including an inlet section with an inlet end communicating with an exterior inlet section in the exterior building wall and an interior section that runs along an interior surface of the condenser housing. The interior section of the plenum communicates with the inlet opening of the condenser housing. The fan generates a flow of air from regions external of the building, through the inlet section of the plenum, through the interior section of the plenum, to the condenser coil in the condenser housing and subsequently through the exterior outlet section in the exterior wall.

A drainage tray for collecting condensate from a heat pump is disclosed, where the heat pump (3) being adapted to be mounted on a support (4) being mountable to at least one supporting structure to carry the weight of the heat pump (2) and the support (4) wherein the tray (2) comprises a peripheral and preferably inclined edge portion (7) defining a central recessed tray portion (8) configured to collect condensate, wherein the tray further comprises a condensate outlet (9) for removing the condensate from the tray (2).

An air-conditioner outdoor device and an air-conditioner unit are provided. The air-conditioner outdoor device includes a casing and a heat exchanger, wherein the heat exchanger is disposed within the casing, a front plate of the casing is provided with an air outlet and two air inlets, the air outlet is located between the two air inlets, the heat exchanger is positioned closer to the front plate relative to a rear plate of the casing and faces the air outlet, and air flow entering the casing from the air inlets flows out of the casing from the air outlet after flowing through the heat exchanger. The air-conditioner unit comprises the air-conditioner outdoor device. The air-conditioner outdoor device of the present application improves the air intake and outlet manners to facilitate the installation of the air-conditioner outdoor device in a mounting hole through a wall and indoors.

A mounting pad system and method for an HVAC outdoor unit that includes providing a lightweight fillable pad shell containing a gelling material and having securing slots extending from an underside surface to an upper side surface of the shell. The shell is filled with water through a port at its upper surface. Prior to leveling the filled pad on the soil at the site and installation of the outdoor unit, securing straps are inserted into the slots from the underside surface of the shell so as to extend through an upper surface thereof. The filling port is covered when the HVAC unit is placed on top of the pad. One or more securing anchors can be used to anchor the pad to the ground, which are also covered when the HVAC unit is place on top of the pad and an anti-theft cable can be employed to further prevent theft.

A structure for a multi-story building comprises a first passageway constructed internally within a building being configured with a mount for a ducted condenser unit (DCU) of a split type, unitary air conditioning system to achieve a desired level of condenser based heat dissipation and with a plurality of penetrations to accommodate a conduit through which refrigerant circulates between inside and outside units of the air conditioning system; and a second passageway constructed internally within the building for receiving air discharged from the DCU the second passageway terminating at an opening of the building through which the discharged air is exhausted to the atmosphere. The passageways have walls that are essentially closed, with the exception of the wall that is formed with an opening through which the discharged air flows. One or both of the first and second passageways upwardly extends across at least two stories of the building.

The invention relates to an HVAC field device comprising a plurality of HVAC device blocks. The HVAC field device comprises: a) a base HVAC device block comprising: a base housing; an electric motor configured to drive an actuated part, and/or a sensor for the measurement of operational parameters of an HVAC system; a base control module connected to the electric motor, and/or the sensors; a base near field communication (NFC) circuit connected to the base control module; and b) a first add-on HVAC device block comprising: an add-on housing and a first add-on NFC antenna, wherein the base HVAC device block and the first add-on HVAC device block are mechanically connected, and wherein the first NFC antenna is electrically connected to the base HVAC device block.

A heat-exchanger fixing plate fixes a side portion of a heat exchanger to a housing panel of an air-conditioning apparatus, the heat exchanger including a heat radiation fin and a heat transfer tube. The heat-exchanger fixing plate includes a heat-exchanger support portion facing the side portion of the heat exchanger, and having an insertion hole through which a hairpin portion of the heat transfer tube of the heat exchanger is inserted; and a housing-panel fixing portion separate from and fitted to the heat-exchanger support portion fastened with a screw to the housing panel such that the heat exchanger is fixed to the housing panel. The housing-panel fixing portion is made of material having a higher mechanical strength than that of the heat-exchanger support portion, and the heat-exchanger support portion is made of the material having a lower friction coefficient than that of the housing-panel fixing portion.
