摘要： A heating, ventilation, and air-conditioning (HVAC) system comprises an outdoor unit with a fan and a coil, and a controller communicatively coupled to the fan and coil. The controller is operable to receive feedback data from the fan, where the feedback data from the fan corresponds to a power and a speed of the fan. The controller is further operable to store a fan model and a plurality of thresholds and determine a virtual sensor measurement, based at least in part upon the feedback data from the fan and the fan model. The controller is operable to determine that the virtual sensor measurement is greater than a frost threshold or a fouling threshold. The controller is finally operable to, in response to determining that the pressure difference is greater than the frost threshold or the fouling threshold, determine a blocked condition on the coil.

摘要： Provided is a throttle device to decompress a refrigerant cooled by a condenser in a refrigerating cycle and to deliver the refrigerant to an evaporator, where a minimum space between a needle valve and a valve port can be accurately set. Inside a cylindrical main body case including a primary chamber connected to the condenser and a secondary chamber connected to the evaporator, a valve seat member formed with a valve port and a cylindrical guide member integral to the valve seat member are provided. A coil spring to energize the needle valve toward the valve port side is provided inside the guide member. A needle portion of the needle valve protrudes from the valve port toward the primary chamber. A tip portion of the needle portion abuts against a stopper member and the tip portion is thereby positioned.

摘要： An access device for installation to a condensation drainage system, such as a drain line of an HVAC unit, includes a main body with at least one connecting port for sealed, fluid receiving connection to the drainage system and an open top communicating with an interior cavity. A top cover releasably secures to the main body to completely cover the open top. An overflow safety switch is removably held in operable position within the interior cavity and below the top cover. The switch senses the level of condensate liquid accumulating with the interior cavity and sends an electronic signal to disable the condensation producing equipment if the liquid reaches a predetermined level.

摘要： In a refrigerating apparatus using a non-azeotropic refrigerant, the composition is included among the quantities of state of a refrigerant, so that it is difficult to detect the state of the interior of the refrigerant circuit. For this reason, it is difficult to stabilize the operation of the refrigerating apparatus by detecting the state of the interior of the refrigerating apparatus, and avoid the malfunction of the refrigerating apparatus. The cyclic composition of the refrigerating apparatus is detected, and the state of the interior of the refrigerating apparatus is detected accurately by using this cyclic composition. In addition, the refrigerating apparatus is arranged such that in a case where there is a quantity of state which cannot be detected accurately owing to an error or the like of the detected cyclic composition, that value can be detected directly. As a result, it is possible to accurately detect the malfunction of the refrigerating apparatus and avoid this state.

摘要： Apparatus and methods for improving efficiency of a temperature conditioning system which employs a cryogenic liquid. A vapor powered ventilation motor is normally powered by vapor from the low pressure end of the evaporation coils. However, supplemental vapor is provided at start-up to provide immediate ventilation. In addition, vapor which bleeds off valves is cycled through the vapor powered motor or used to maintain a slight positive pressure when the system is shut down.
