  • Patent number: 6644398
    Abstract: A system and method for controlling delivery of conditioned water to a plurality of heat exchangers includes a system controller which gathers information as to the current and future demands for conditioned water by a plurality of zone controllers associated with the plurality of heat exchangers. The system controller is operative to provide conditioned water to the heat exchangers even though current demands for conditioned water may not be sufficient to require the provision of conditioned water to the heat exchangers. The system controller analyzes current demands for conditioned water in combination with future demands for conditioned water to determine if the combined demands exceed a minimum level or number of demands necessary to authorize provision of conditioned water to the heat exchanger.

  • Patent number: 6641054
    Abstract: A thermostat is provided with an image projection capability that allows images concerning the operation of the thermostat to be projected onto a surface in the vicinity of the thermostat. The image projection is preferably accomplished by directing an internally generated image to an image enlargement device which thereafter projects an enlarged image onto the surface in the vicinity of the thermostat. The surface that receives the projected image is preferably defined by a screen affixed to the wall that the thermostat is mounted to.

  • Patent number: 6634566
    Abstract: A thermostat is operative to note the current temperature at time of entering into a setback of one or more previously established setpoints. The thermostat is also operative to note any newly defined setpoints. The thermostat also notes whether the setback is to occur in a heating or cooling mode of operation. The thermostat maintains a record of the aforementioned entry conditions mount of time the thermostat participates in a requested setback. The thermostat also preferably notes one or more setpoints and sensed temperature occurring at the end of an implemented setback as well as the ending heating or cooling mode of operation. A record of temperature conditions, mode of operation and elapsed time for each setback is stored for retrieval by a remotely located entity in communication with the thermostat. The entity is usually an energy provider. This record is available for retrieval at any time, including a time when the thermostat is presently implementing a setback.

  • Patent number: 6592346
    Abstract: A compressor includes a particularly shaped discharge valve which extends into the discharge port. The shaped valve includes a convex portion on the seat side of the valve which extends downwardly into the discharge port. The shaped valve furthermore includes a concave portion on the seat side of the valve that begins where the convex portion ends. The beginning of the concave portion on the seat side of the valve is located so as to prevent flow separation of the refrigerant when flowing along the convex portion of the valve as it leaves the compression chamber of the compressor.

  • Patent number: 6549870
    Abstract: A thermostat receives requests to enter into setback modes of operation whereby at least one setpoint normally used by the thermostat is changed. The thermostat is operative to compute the integral of change in setpoint temperature over time during each setback mode of operation. The thermostat is also operative to maintain a running total of such computed integrals of change in setpoint temperature over time in order to respond to any request for such computed integrals. The thermostat is furthermore operative to set the total of such computed integrals of change in setpoint temperature over time equal to zero in response to a request to clear the total of such computed integrals of change in setpoint temperature over time.

  • Patent number: 6470700
    Abstract: A grill for an air conditioning unit has one or more grill members wrapped with wire so as to present a varying topographical surface to the flow of air over the grill members. The resulting grill member profile that is presented to the air flow reduces vortex shedding noise that would otherwise occur without the wire wrapping. Various wire wrappings are disclosed which produce the desired effect of reducing the vortex shedding noise.

  • Patent number: 6448896
    Abstract: An electronic system for monitoring the condition of the filter in an HVAC unit includes a controller which issues at least one command to a circuit for the motor of the fan producing airflow through the filter. The command to the driver circuit is associated with a desired run speed for the fan. The controller is operative to compute the speed of the fan following issuance of the command to the motor drive circuit. This computed speed is compared to a predetermined fan speed that would normally occur when the filter is dirty. The electronic system is operative to generate a warning in the event that the computed fan speed does not compare favorably with the predetermined fan speed.

  • Patent number: 4687152
    Abstract: It is convenient to supply electrical or electronic components for placement on tapes; however it has proved difficult to satisfactorily handle tapes for carrying large components. Use of wide tapes to feed larger components is facilitated by using a drive belt (48) to rotate at a sprocket wheel (44) to feed the tape (38,40), a drive wheel (52) to move the belt, and drive means conveniently a ratchet wheel to cause the drive wheel (52) to rotate through a predetermined angle to feed the tape a distance equal to the spacing between the components on the tape. Wide tape can conveniently be disposed of after unloading by using means (88,90) for severing the tape (38) immediately downstream of an unloading position, and means for collecting the severed tape preferably comprising a duct (84) through which a current of air flows to carry the severed tape to a remote receptacle (85).
