摘要： Described herein is an improved HVAC system and method of configuring an HVAC system for cost-effective installation and energy efficient operation for multiple unit residential buildings. In one example embodiment, a mechanical room is sized to simultaneously house most of the HVAC equipment but to also advantageously operate as the HVAC system's air mixing chamber for a wall-mounted temperature and humidity conditioning unit and a blower assembly, based on maximum heating and cooling loads and the minimally required air flow requirement for a defined living space. This advantage allows for elimination of one or more mechanical plenums for air mixing space as well as flexibility in locating HVAC components in the space provided.

摘要： A distributed heating and cooling system with air-duct, vent register or vent-diffuser based, collaborative fan devices to dynamically redistribute warmer or cooler air from a space, through an air-duct system of a building, into another space within the building so as to achieve the desired temperatures in the spaces to which these devices are connected. A bi-directional fan would move the air within a room into or out of an air-duct system. The system and method can create a multi-directional air flow within the building. Different fan devices work within different collaboration zones to create a distributed system for heating and cooling.

摘要： The present disclosure relates to a method of controlling a ventilatory volume for inhibiting a release of a harmful gas such as an offensive odor or a toxic substance from a closed-type duct. The method of controlling a ventilatory volume is characterized in that (i) the closed-type duct is divided into a single main duct and multiple branch ducts in a planned area and depends on a harmful gas prevention closed-type duct model in which a negative pressure may be formed by a separately provided means for forcedly discharging gas, (ii) in a state in which no forced gas discharge from the closed-type duct is made, the harmful gas is determined as a standard flow velocity by comparing inverse velocity values of natural positive-pressure flow velocities according to a difference in temperature, a difference in concentration, a difference in elevation of the duct, a stack effect, and the like, (iii) the standard flow velocity is assigned in a lump to flow velocities in the single main duct and the multiple branch ducts provided in the closed-type duct, a sum of the flow rate in the main duct and the flow rate in the multiple branch ducts is basically determined as a ventilatory volume by the means for forcedly discharging gas, and particularly, only the flow rates in the branch duct at the junction points are corrected and determined in a lump based on a ratio of a pressure loss in the main duct to a pressure loss in the branch duct. The method of controlling a ventilatory volume may be applied to the closed-type duct having various usages and shapes and may provide a quantitative criterion related to a minimum ventilatory volume required to inhibit a release of a harmful gas, thereby reducing costs, maximizing operational efficiency, and an operational criterion practical to various types of ventilation devices.

摘要： Architectures and techniques are presented that can more efficiently route excess air flow by intelligently selecting the zones to which the excess air flow is to be routed. Excess air flow results from an HVAC device providing (e.g., at a minimum setting) a volume of air that is greater than what is demanded by a zone that triggers activation of the HVAC device. As one example, excess air flow can be routed to a zone or zones that are determined to be most likely to trigger a subsequent activation condition that would cause the HVAC device to be activated again at a future time.

摘要： The present specification relates to a system for managing the condition of air in an enclosed environment comprising a flow path adapted to circulate a flow of air through the enclosed environment, the flow of air comprising at least one of a first portion comprising a gas comprising oxygen and a second portion comprising indoor air from the enclosed environment. The flow path selectively provides the portions. An air processing assembly is adapted to receive the flow of air. A first and a second air processing element is provided. A control system is adapted to determine the first portion of gas comprising oxygen and the second portion of indoor air from the enclosed environment and control the selectively coupling of the air processing elements to the flow path.

摘要： A controlled dilution fluid flow pattern is described. In an embodiment, a fluid supply device is configured for controlling a pattern of a flow of a fluid within a critical room. The critical room comprises a critical area subject to contamination. A first fluid supply nozzle is configured to provide a first fluid supply jet to provide a first flow of the fluid towards a substantial center of the critical area. A second fluid nozzle is configured to provide a second fluid supply jet to provide a second flow of the fluid towards a perimeter of the room. A momentum of the first fluid supply jet and a momentum of the second fluid supply jet are adjusted so that the substantial center of the critical area is flushed by the first flow and penetration of the second flow into the substantial center of the critical area is generally prevented. In other embodiments, a HVAC system and method are discussed along with the features of the device.

摘要： A pressure control device for controlling a compressor includes a pressure sensor configured to measure pressure of a pressure line and a processing circuit. The processing circuit is configured to receive the measured pressure of the pressure line from the pressure sensor and control the compressor based on a set-point and the measured pressure. The pressure control device includes a mechanical switch sensitive to the pressure of the pressure line and configured to move between an open position and a closed position responsive to the pressure of the pressure line. Movement of the mechanical switch into one of the open position or the closed position causes the compressor to turn off and overrides the control of the compressor by the processing circuit.
