Abstract: A method of monitoring a HVAC system to detect erroneous sensor installation. The method includes determining whether a circulation fan has been operational for a first predetermined time interval. If the circulation fan has been operational for the first predetermined time interval, determining whether a cooling demand is present. If the cooling demand is present, determining whether the HVAC system has been conditioning air for the first predetermined time interval responsive to the cooling demand. If the HVAC system has been conditioning the air for the first predetermined time interval, determining whether a difference between an indoor air temperature value corresponding to an enclosed space and an air temperature value from a discharge air temperature (DAT) sensor is greater than a predetermined temperature value. If the difference is not greater than the predetermined temperature value, forwarding a message indicating that the DAT sensor positioned within a duct of the HVAC system is improperly installed.

Abstract: It is an object to obtain an air conditioner capable of suppressing rise of compressor discharge temperature and individually controlling cooling capacity of a plurality of respective indoor units. For this purpose, the air conditioner is a multi-room air conditioner, in which a refrigeration cycle is formed by connecting an outdoor unit 100 having an outdoor heat exchanger to the plurality of indoor units 200 and 300 having indoor heat exchangers 201 and 301 and indoor expansion mechanisms 203 and 303 using a liquid pipe 121 and a gas pipe 122. Further, as refrigerant circulating through the refrigeration cycle, R32 or mixed refrigerant containing 70 mass % or higher percent of R32 is used. Further, a temperature difference detection device to detect an air temperature difference between inlet-side air and outlet-side air in the respective indoor heat exchangers of the respective indoor units is provided. The cooling capacity in the respective indoor units is controlled by regulating the indoor expansion mechanisms of the respective indoor units based on the air temperature difference in the indoor units detected with the temperature difference detection device.

Abstract: A remote controller controlling an air-conditioning apparatus includes: a main part, a three-axis acceleration sensor; a normality determination part that determines whether an installation state of the remote controller is in a normal installation state or in an abnormal installation state, based on a detection value of the acceleration sensor; a stationary state determination part that determines whether the installation state is in a stationary state; a vibration determination part that determines whether a vibration occurs; a thermo sensor; and a control part that controls the air-conditioning apparatus. The main part includes a back face, a front face, and a bottom. The remote controller is in the abnormal installation state due to a shape and a centroid when the remote controller is placed on a horizontal surface. The control part performs a limited control that includes limitation of a control of the air-conditioning apparatus based on the environment temperature. A remote controller controlling an air-conditioning apparatus includes: a main part, a three-axis acceleration sensor; a normality determination part that determines whether an installation state of the remote controller is in a normal installation state or in an abnormal ...more ...less

Abstract: A computer-implemented system for generating a controller to control a heating, ventilation, and air conditioning (HVAC) system decomposes a model of the HVAC system into a collection of transformed models defining relationship between input channels and output channels with decoupled dynamics, such that a single input channel affects only one corresponding output channel Each input channel is defined by a weighted combination of control inputs to the HVAC system, and each output channel is defined by a weighted combination of temperatures affected by operation of the HVAC system. The collection of decoupled transformed models includes a first transformed model modeling dynamics of the outdoor unit as a relationship between uniform control for the set of indoor units and the average temperature in the set of rooms and includes a set of second transformed models. Each second transformed model models a difference between room dynamics and room coupling dynamics. The system generates a decouple controller for each transformed model to form a collection of decoupled controllers, wherein, each decouple controller defines a relationship between measurements the output channel and inputs to the input channel of the corresponding transformed model.
