An example heat pump system includes a low-height cabinet configured to be mounted to a ceiling. The low-height cabinet includes a frame and a plurality of panels that define a compressor compartment, a blower compartment, and a plenum compartment. The frame includes one or more dividers that separate the blower compartment, the plenum compartment, and the compressor compartment from each other. The example heat pump system also includes a compressor installed horizontally in the compressor compartment, a heat exchanger installed vertically in the compressor compartment, a blower assembly installed in the blower compartment, and an air coil installed in the blower compartment.

A heating, ventilation, and/or air conditioning (HVAC) packaged unit includes a first refrigerant circuit component configured to change a temperature or a pressure of a refrigerant flowing through the first refrigerant circuit component and a second refrigerant circuit component configured to change a temperature or a pressure of the refrigerant flowing through the second refrigerant circuit component. The first and the second refrigerant circuit components are within a common refrigerant circuit that is disposed within a common support structure. The HVAC packaged unit also includes an interconnection conduit having a length formed from aluminum, a first end segment coupled to a first end of the length, and a second end segment coupled to a second end of the length. The first end segment and the second end segment are each formed from copper, and the interconnection conduit extends between the first refrigerant circuit component and the second refrigerant circuit component.

This application discloses a passive ventilation system, including intake and exhaust, both driven by natural wind invariably regardless of wind direction, without a necessity for electric or other power supply. The intake assembly is an improved wind catcher, with multiple wind collectors arranged around a common chamber, each having an outer end open to ambient air, an inflow valve, and an inner end connecting the common chamber, which connects a conduit allowing fresh air and positive pressure to enter an indoor space being ventilated. The exhaust assembly is an augmented negative pressure generator to induce stale air to exit the space being ventilated through another conduit. The inflow and outflow conduits are configured to form a pipe-in-pipe or shell-and-tubes heat exchanger to mitigate heating or cooling energy loss and draft discomfort. Rainwater proof and condensation draining mechanisms, and optional inflow air filter mounting, are also provided.

An air conditioner including: a housing communicating with a space in which a window covering is installed, and including a suction port through which air is suctioned from the space and a discharge port through which air is discharged into an indoor area; a heat exchanger configured to exchange heat with the air suctioned through the suction port; a blower fan allowing air to be suctioned through the suction port or allowing air to be discharged through the discharge port; and a guide panel provided at the suction port to guide the window covering to prevent the window covering from covering the suction port.

An interchangeable duct seal is provided. The interchangeable duct seal includes a first panel, the first panel having a first support structure and a first material attached to the first support structure; and a brace configured for securing the first panel to a structure; wherein the first panel includes a first opening and is configured to connect to a first duct and/or allow the first duct to pass through the interchangeable duct seal. The interchangeable duct seal may also include a second panel or multiple panels. Related kits and methods are also provided.

An air conditioner indoor unit includes a chassis provided with a first installation position and a second installation position, an indoor heat exchanger provided at the first installation position, a compressor in communication with the indoor heat exchanger and provided at the second installation position, and a first-stage elastic vibration reduction structure and a second-stage elastic vibration reduction structure. An installation foot is provided at a bottom of the compressor and is connected to the chassis. The first-stage elastic vibration reduction structure is provided between the installation foot and the second-stage elastic vibration reduction structure. The second-stage elastic vibration reduction structure is provided between the first-stage elastic vibration reduction structure and the chassis.
