An air conditioning system includes: an air conditioner that generates conditioned air by heat exchange with a refrigerant and supplies the conditioned air to an air conditioning target space; a refrigerant sensor that detects refrigerant leakage; a ventilator that ventilates the air conditioning target space; and a controller. The ventilator includes: a total heat exchanger; a first air supply path and a first air exhaust path that connect the air conditioning target space and an outside of the air conditioning target space via the total heat exchanger; a second air supply path that connect the air conditioning target space and the outside of the air conditioning target space without passing through the total heat exchanger; an air supply fan that supplies air from the outside of the air conditioning target space into the air conditioning target space via the first air supply path and the second air supply path.

A quick ceiling fan mounting bracket with a safety protection structure has a bracket, two guide rails and an elastic engaging member. The bracket is configured to connect a junction box and a ceiling fan motor unit. The junction box is locked with two locking members. When installed, the locking members are half locked into locking holes of the junction box, and the heads of the locking members are positioned at positioning holes and a force is applied to the elastic engaging member for the locking members to pass through the guide rails. When the head of the locking member is displaced, an engaging portion of the elastic engaging member is against the head of the locking member to achieve the effect of safety protection.

A multifunction adaptive whole house fan system can include a whole house fan to pull large volume of air through a building structure. The whole house fan can pull air from a motorized window or damper into the building structure and expel air through an attic. The system can monitor the environment to operate the whole house fan when desired conditions are present in coordination with other systems of the building structure to reduce overall energy consumption.

A cooling and ventilation outlet is described, including a shell configured to connect to an HVAC duct and an inner body that may be securely attached within the shell such that air from the HVAC duct passes through the inner body. The inner body may include: a directable air output nozzle, a first actuator configured to control a direction of the nozzle, an adjustable damper, a second actuator configured to control airflow through the inner body by actuating the adjustable damper, an indicator that may include at least one controllable visual element, a pressure sensor configured for use in determining airflow through the inner body, and circuitry including a network interface. The circuitry is configured to accept commands over a network, to accept readings from the pressure sensor, and to control the first actuator, the second actuator, and the indicator.

A system for air handling, the system includes a pipe comprised of plastic having an oval cross-section. The system may further include a register boot comprised of plastic having a main body with a first opening and a second opening wherein the first opening has an oval cross-section for connection with an oval pipe and wherein the second opening is generally rectangular for fitting a register cover. The system may further include a fitting having a first end and a second end, the first end having a round opening and a second opening having an oval cross-section and a main body between the first end and the second end. The main body may be sized and shaped such that the round opening is presented orthogonally to the second opening. The system may further include a t-fitting having a first segment with a first opening attached to a second segment orthogonal to the first segment, the second segment having first and second opposite openings.

An assembly for controlling the position of air inlets of an enclosure including an actuation rod which moves laterally and is positioned above and parallel with the air inlets, one or more actuation cables, where the first end of each actuation cable is attached to the actuation rod and the second end of each cable is attached to one or more of the air inlets and lateral movement of the actuation rod causes vertical movement of the actuation cables and attached air inlets.
