Abrégé

A system for managing drainage of heat pump coil condensate using a building's legacy heat piping infrastructure. The system includes a drainage pan that accumulates condensate and directs it into condensate piping. The condensate piping feeds the condensate into the building's legacy heat piping infrastructure, preferably after treating the condensate with a neutralizer to reduce its acidity. The system also includes a system control for monitoring the accumulated condensate levels and the status of the legacy heating system to determine when to open a flow control means allowing the condensate to drain from the condensate piping into the building's legacy heat piping infrastructure.

A heat recovery ventilator (HRV) and/or energy recovery ventilator (ERV) that integrates with a residential capacity air handling unit (AHU) is embodied in a small footprint HRV or ERV unit that connects directly to the return side of an AHU and to outdoor air inlet and exhaust ducts. The ventilator includes a control system incorporating a processor and sensors that control the operation of the system to provide desired ventilation flow rates under varying conditions.

Abrégé

A system for determining the relative space heating energy contribution of different tenant spaces in a multiple tenant building that is heated via a central steam piping distribution system. A steam piping distribution system is connected to a central heat source such as a steam boiler plant or a local utility district steam service. The steam distribution system includes terminal units located throughout the building which deliver heat to different spaces. Data collected at regular intervals from sensors located throughout the building are analyzed by a computer in order to calculate the fraction of the overall building's steam use that is delivered to particular tenant spaces over a given interval in time.
