摘要： System recognition is performed on devices connected to an identical system without recognizing a device of a different system as a device of the identical system in high-frequency communication. In a device network system, an outdoor unit selected from among all outdoor units of a first network performs a recognition process on the outdoor units and indoor units of the first network. In the first network, communication between individual devices including the outdoor units and the indoor units is performed by using a high frequency, and the recognition process performed by the selected outdoor unit uses a recognition signal having a low frequency.

摘要： Provided is an air conditioning system capable of detecting in advance a device that consumes more power than the power that can be fed by a power feed unit. An air conditioning system includes a refrigerant cycle, a power feed unit, and a controller. The refrigerant cycle includes an outdoor unit and a plurality of indoor units. In a case where a power source for at least one indoor unit of the plurality of indoor units has been interrupted, the power feed unit feeds power from an auxiliary power source to the indoor unit for which the power source has been interrupted. When a predetermined device has been connected to at least part of the plurality of indoor units and the power feed unit, the controller performs deactivation of at least one of functions of the device.

摘要： The disclosed embodiments relate to a system that provides a polymer heat exchanger with internal microscale flow passages. The system includes a set of plates comprised of a polymer that includes internal microscale flow passages, which are configured to carry a liquid. The set of plates is organized into a stack, wherein consecutive plates in the stack are separated by fins to form intervening air passages. The system includes a liquid flow pathway, which flows from a liquid inlet, through the internal microscale flow passages in the stack of plates, to a liquid outlet. It also includes an airflow pathway, which flows from an airflow inlet, through the intervening air passages between the consecutive plates in the stack of plates, to an airflow outlet. The liquid flow pathway flows in a direction opposite to a direction of the airflow pathway to provide a counterflow design that optimizes heat transfer between the liquid flow pathway and the airflow pathway.

摘要： A system for air-conditioning and hot-water supply selectively performs cooling and heating operations. The system includes: an outdoor unit having a compressor and an outdoor heat exchanger; indoor units each of which is connected to the outdoor unit and includes an indoor heat exchanger; a hot-water supply unit connected to the outdoor unit and arranged in parallel to the indoor units and including a refrigerant-water heat exchanger; and a controller monitoring an occurrence of a hot water request for hot-water supply from the hot-water supply unit during the cooling operation performed at at least one of the indoor units, and then to start the heating operation in accordance with the hot-water request. The controller also monitors an occurrence of an indoor-unit request from any one of the indoor units and resumes the cooling operation where the request is an increase request for an increase of load of the cooling operation.

摘要： An air handling unit (AHU) system is provided and includes an AHU. The AHU includes an enclosure formed to define an inlet and at least one outlet downstream from the inlet, an air supply system to drive an air flow through the enclosure from the inlet to the outlet and a misting system operably coupled to the AHU. The misting system is configured to spray high pressure, cold water mist that includes mist droplets into a portion of the enclosure upstream from the at least one outlet whereupon heat transfer occurs directly between the mist droplets and air prior to the air reaching the outlet.

摘要： Internal control devices (41A to 41D) included respectively in air conditioners (10A to 10D) in an air conditioning system (1) are communicably connected one by one correspondingly to external control devices (42A to 42D). Each of the external control devices (42A to 42D) is configured to execute command generating operation of generating an operation command to a corresponding one of the air conditioners (10A to 10D). The external control devices (42A to 42D) constitute an external control system (50). In the external control system (50), one of the external control devices (42A) functions as a master control device configured to execute the command generating operation whereas remaining ones of the external control devices (42A to 42D) other than the external control device (42A) functioning as the master control device function as sub control devices configured not to execute the command generating operation.
