    Abstract: Embodiments of the disclosure relate to systems and methods to evaluate performance of a fluid transport system. Towards this end, a performance report of the fluid transport system can be generated by estimating various performance parameters at an outlet of a heat exchanger in lieu of using sensor data obtained directly from the outlet of the heat exchanger. Specifically, in one exemplary implementation, sensor data is obtained from an inlet of the heat exchanger and an outlet of a downstream element that is coupled to the heat exchanger, for estimating the various performance parameters at the outlet of the heat exchanger. The estimated performance parameters can then be combined with empirical data and predictive data for generating the performance report of the fluid transport system.

  • Patent number: 9612188
    Abstract: An air purifier is presented with a sensor controlling a motorized fan, wherein the sensor continuously and automatically adjusts the sensitivity setting of the sensor as the quality of air being purified changes. The average air quality readings of the air passing through an air purifier are monitored over a designated time period and, as the quality fluctuates, the sensitivity of the sensor is automatically adjusted. If the air quality is poor (i.e. a high particulate count), the sensitivity of the sensor will be adjusted to a less sensitive setting (i.e. allowing higher fan speeds so that more air can be moved through the filter) and, if the air quality is good (i.e. a low particulate count), the sensitivity of the sensor will be adjusted to a more sensitive setting (i.e. setting a lower maximum fan speed because not as much air needs to move through the filter).

  • Patent number: 8484988
    Abstract: A heating/cooling system includes a closed circuit refrigeration system including an evaporator. Water circulating through a closed water circuit exchanges heat with refrigerant in the evaporator, cooling the water for a cooling application. The water can also be heated by a boiler, and the heated water is used to heat a space. A water pump flows the water through the water circuit. When a current sensing relay detects a power failure, a boiler control algorithm is initiated to “trick” a motor of the compressor into believing the heating/cooling system is operating in a heating mode. Therefore, a compressor failure alarm is not generated. The water pump is powered by a battery pack during the power failure. Water continues to flow through the water circuit, preventing the water from freezing.

  • Patent number: 8042347
    Abstract: A compressor inlet pressure estimation apparatus for a refrigeration cycle system is disclosed. An electronic control unit 14 uses Tefin_lag(N) as an actual corrected temperature Tefin_AD(N) during a period Tp1 included in the timing t1 to t2. During a period Tp2 included in the timing t1 to t2, Tefin_fwd(N) is used as the actual corrected temperature Tefin_AD(N). Thus, a highly accurate corrected temperature Tefin_AD(N) can be determined over the on period (t1 to t2) of a compressor 2. In addition, Tefin_fwd(N) is used as the actual corrected temperature Tefin_AD(N) during the off period (t2 to 3) of the compressor 2. As a result, a highly accurate corrected temperature Tefin_AD(N) can be determined over the whole period including the on and off periods of the compressor 2. In this way, a highly accurate estimated value Ps_es(N) of the refrigerant inlet pressure of the compressor 2 can be determined.

  • Publication number: 20110239671
    Abstract: A method of providing cooling by a cooling system to a computer data center. The method includes providing a plurality of air-and-water radiators and one or more chillers, the chillers each having a first side in fluid communication with a chilled water loop and a second side in communication with a condenser water loop. The method also includes circulating a first portion of return water coming from the computer data center to a first subset of the air-and-water radiators and through the condenser water loop, circulating a second portion of the return water from the computer data center to a second subset of the air-and-water radiators and through the chilled water loop, and circulating the first portion and the second portion of the return water to the computer data center as cooled supply water.

  • Patent number: 8006507
    Abstract: A system and method is provided for controlling the operation of secondary coolant pump(s) in a refrigeration system having a secondary coolant system that circulates the coolant to applicable cooling loads, and a primary refrigeration system that chills the coolant in the secondary coolant system. The system and method for controlling the pumps measures the pressure of the plurality of secondary coolant fluid loops, sorts the measurements to identify a secondary coolant fluid loop with a pressure farthest from a setpoint, and adjusts pump speed to compensate for the critical loop (i.e., the secondary coolant fluid loop with a pressure furthest from the setpoint).

  • Patent number: 7832214
    Abstract: An air-conditioning device includes a pump for sending a thermal medium, a thermoelectric conversion unit for absorbing heat from the thermal medium, a target setting unit for setting a target cooling value, and a controlling unit. The controlling unit increases a flow amount of the thermal medium to be larger than a predetermined amount and stops the thermoelectric conversion unit from absorbing heat, when the target cooling value is smaller than a predetermined value. The controlling unit increases a heat-absorbing amount of the element and keeps the flow amount of the thermal medium to be larger than the predetermined amount, when the target cooling value is equal to or larger than the predetermined value.
