摘要： A diagnostic method for testing a fan or pump assembly in a refrigerant system includes steps of operating a controller to periodically shut down, or reduce fan or pump speed for a short period of time, while continuing to operate the refrigerant system. Changes in an operating condition such as pressure, temperature, electric current or operating speed are monitored. If expected changes do not occur, a determination can be made that a fan or pump assembly is malfunctioning.

摘要： There is provided a refrigerant system. First and second transducers are positioned within the refrigerant system to measure respective operational characteristics. There is a timer that determines that a shutdown has occurred for a specified period of time; and a comparator that compares an output of the first transducer to an output of the second transducer after that specified time and determines whether the outputs of the first and second transducers are within a tolerance band of each other. If the readings are not within tolerance band, then the transducer failure is detected and a warning/alarm requiring operator attention is issued.

摘要： A tandem compressor system is utilized that receives refrigerant from a common suction manifold, and from a common evaporator. From the compressors, the refrigerant passes to a plurality of condensers, with each of the condensers being associated with a separate zone for heat rejection, preferably at different temperature levels. Each of the condensers is associated with at least one of the plurality of compressors. A reheat coil is associated with the evaporator to improve comfort level in the environment to be conditioned. Multiple reheat circuits associated with separate condensers are employed to provide various stages of reheat or to condition separate environments. By utilizing the common evaporator, a plurality of condensers, and the reheat coils, the ability to independently control temperature, humidity and amount of heat rejection to a number of zones is achieved without the requirement of having dedicated circuits with multiple additional components. Thus, the overall system cost and complexity is significantly reduced and its operational and control flexibility is improved.

摘要： A closed-loop reheat circuit decoupled from a main refrigerant circuit is provided as part of a refrigerant system. In the closed-loop reheat circuit refrigerant is flown through an auxiliary heat exchanger, at which it transfers heat to refrigerant in the main circuit, increasing its cooling and dehumidification potential prior to entering an evaporator. The closed-loop circuit also includes a reheat heat exchanger that is placed in the path of at least a portion of airflow having passed over an evaporator. The reheat heat exchanger reheats air supplied to a conditioned space to a desired temperature after sufficient amount of moisture has been removed from the air in the evaporator to provide a comfortable humidity level. By utilizing the closed-loop reheat circuit, a control for the overall refrigerant system becomes less complex and more flexible, and the refrigerant system operation turns out to be more reliable and satisfying a variety of environmental conditions and potential applications. Various features and options of the decoupled reheat circuit concept are also disclosed.

摘要： A refrigerant system has a controller associated with it that determines an equilibrium pressure when the system is inactive. The controller determines if the equilibrium pressure differs from an expected equilibrium pressure corresponding to a current ambient temperature and the selected refrigerant type. When the difference exceeds a selected threshold, the controller determines that the amount of refrigerant within the circuit is below a desired level. In one example, the controller provides an indication of a low charge amount. The disclosed technique allows early detection of refrigerant charge loss and differentiation between loss-of-charge and other failure modes. Consequently, system performance is enhanced, component damage is prevented, service interruptions and maintenance are reduced, exhaustive troubleshooting is avoided and potential exposure to refrigerant substances is minimized.

摘要： In an air conditioning system including a compressor, a condenser, and an evaporator, a process includes the steps of feeding discharged refrigerant from the compressor to the condenser so as to provide a condensed refrigerant flow; splitting the condensed refrigerant flow into a main flow and an auxiliary flow wherein the auxiliary flow includes between about 8 and about 12% wt. of total mass flow rate of the condensed refrigerant flow; reducing temperature and pressure of the auxiliary flow so as to provide an economizer flow; passing the economizer flow and the main flow through a heat exchanger so as to provide a sub-cooled main flow and an economizer discharge flow; feeding the economizer discharge flow to the compressor; and feeding the sub-cooled main flow through the evaporator to the compressor. The system and process in accordance with the present invention advantageously allow for parameter optimization, circuit combination, and performance improvement through integration of economized and non-economized circuits.
