摘要： An electrically controlled valve which can be operated using a programable controller. A cooperating pair of the electrically controlled valves can be used in a Regenerative Thermal Oxidizer (RTO). The electrically controlled valve has two seats, and a blade which can move between a first position contacting the first seat and a second position contacting the second seat. The blade is moved by an actuator which is controlled by a variable frequency drive (VFD). A control computer continuously monitors the operation of both valves and halts operation of the system upon detecting a fault (error). The motion of the blade is programmed such that force of impact on the seat is reduced. Once the blade is seated, a brake is engaged which maintains the stationary position while utilizing relatively low power.

摘要： Embodiments include systems and methods for heating water and cooling air simultaneously, as well as other simultaneous heating and cooling operations. An example variable refrigerant flow conditioning system includes an outdoor unit having a compressor, a condenser coil, and a fan, a water heater coupled to the outdoor unit, a first air conditioning unit coupled to the outdoor unit, and a controller. The controller may be configured to determine that a cooling operation mode is active during a first time interval, cause vapor refrigerant to be directed from the outdoor unit to the water heater and liquid refrigerant to be directed from the outdoor unit to the first air conditioning unit, determine that a heating operation mode is active during a second time interval, and cause the vapor refrigerant to be directed from the outdoor unit to both the water heater and the first air conditioning unit.

摘要： A water heating system can include a water heater having a tank, an inlet line, and an outlet line, where the inlet line provides unheated water to the tank, and where the outlet line draws heated water from the tank. The water heating system can also include multiple sensing devices, where each sensing device of the plurality of sensing devices measures a parameter associated with the tank. The water heating system can further include a controller communicably coupled to the plurality of sensing devices, where the controller determines an amount of heated water in the tank based on measurements made by the plurality of sensing devices.

摘要： A heating, ventilating and air conditioning (HVAC) assembly that includes a duct and a coil assembly coupled to the duct. A supply line and return line are connected to the coil assembly. A first hanger assembly encircles the supply line, and a second hanger assembly encircles the return line. A support bracket has a first raised channel with a hole and second raised channel with a hole. A first threaded connector is secured using a square nut located in under the raised channel of the bracket, and a second threaded connector is connected to the threaded hole of the second hanger assembly and the second hole in a raised channel of a bracket and secured using a square nut located in under the raised channel of the bracket.

摘要： This invention relates to a new and useful device for monitoring the heating and cooling energy consumed by a single unit of a multi-unit apartment or office building. The monitoring circuit is responsive to a thermostat located in each unit as well as the speed of a blower; said blower being used to force the heated or cooled air into the unit. The monitoring circuit is comprised of an integrating circuit coupled to the thermostat and/or fan speed circuit. A pulse generator is electrically coupled to the integrating circuit; the pulse generator generates a pulse after a predetermined amount of current flows into the integrating circuit. The extended pulse is then transmitted to amplifier means which in turn transmits said signal to a pulse counter.
