    Abstract: A surface cleaning apparatus has a cyclone bin assembly having a cyclone chamber. The cyclone chamber with a physical filtration member defining the cyclone air outlet. The physical filtration member extends from the cyclone air inlet end of the cyclone chamber towards an openable bottom end of the cyclone chamber. The physical filtration member comprises a conical section which decreases in diameter towards the openable bottom end of the cyclone chamber, wherein a projection of the conical section meets at a location that is positioned between the physical filtration member and the openable opposed end. An openable bottom end of the cyclone bin assembly and the openable bottom end of the cyclone chamber are openable concurrently.

    Abstract: Various embodiments are described herein for an environmental control system. In one example embodiment, the system is an HVAC system including an HRV or ERV unit, a first distribution system, and an ambient energy distribution system. The first distribution system has a first end in thermal communication with the HRV or ERV unit and a second end in thermal communication with the interior of a domicile. The ambient energy distribution system extends between first and second locations in the domicile and is isolated from fluid flow communication with the first distribution system. The ambient energy distribution system transfers heat between the first and second locations.

    Abstract: An arrangement of multiple environmental control systems for a multi-unit structure has a first environmental control system installed in a first unit, a second environmental control system installed in a second unit, a system monitor in communication with each of the environmental control systems and a firewall. Each environmental control system has a control unit coupled to the system monitor through the firewall that prevents unauthorized devices from accessing the respective control unit and a HVAC system device coupled to the respective control unit through the firewall. For each unit, a local user device that is located inside the unit is coupled to the control unit through a local communication interface, and an external user device that is located outside the unit communicates with the control unit through the firewall.
