摘要:
An objective is to realize an air conditioner in which the amount of consumed electric power can be integrated without using an exclusive electric-power-amount counter, and a control line for measuring the amount of the electric power can be shortened. Commercial electric power is supplied to an outdoor unit 1 and an indoor unit of the air conditioner through a Watt-hour meter 3, for measuring the amount of electric power supplied to the outdoor unit 1 and the indoor unit, having a transmitter for transmitting pulse signals, and through an electric power line 4. The Watt-hour meter 3 and the outdoor unit 1 are communicatively connected to each other through a control line 5. The outdoor unit 1 and the indoor unit are communicatively connected to a centralized controller through a transmission line 7. Especially, the outdoor unit 1 includes a Watt-hour meter connection circuit 10 for receiving a signal related to the amount of the electric power from the Watt-hour meter 3, and a controller 11 for integrating the amount of electric power based on the received signal related to the amount of the electric power.
摘要:
A first communication section in an optical communication interface communicates with outdoor units and indoor units using a first communication method. A central management controller communicates with the optical communication interface using the first communication method and manages the outdoor units and the indoor units according to the first communication method. A second method communication section in a second communication method indoor unit of a different manufacturer communicates with a second method communication section in a second communication method outdoor unit using a second communication method. The optical communication interface and the second communication method indoor unit exchange information by optical communication with each other using respective optical communication sections.
摘要:
Even at spots, such as a window side and the back side of a room, where air conditioning loads are different from each other, comfortable air conditioning is obtained at low cost using a common air conditioning unit. One indoor apparatus and wireless transceiver having a ZigBee-compliant transmission device are installed in the room. Sensor units having temperature/humidity sensors and ZigBee-compliant wireless transceivers are installed at plural indoor spots where the air conditioning loads are different from each other. A controller in the indoor-apparatus receives sensor information (temperature/humidity information) via the wireless transceivers from the sensor units, and computes a weight average based on the sensor information and weight values that are pre-stored in the storing devices and that correspond to the sensor units. Using the computed value as a control value, the controller controls an air conditioning unit.

Even at spots, such as a window side and the back side of a room, where air conditioning loads are different from each other, a comfortable air condition is obtained at low cost using a common air conditioning unit.One indoor apparatus 310 and wireless transmitting means 400 having a ZigBee-compliant transmission device are installed in the room. Sensor units 410a to 410n having temperature/humidity sensors and ZigBee-compliant wireless transmitting means are installed at plural indoor spots, such as the window side and the back side, where the air conditioning loads are different from each other. Controlling means 311 in the indoor-apparatus 310 receives sensor information (temperature/humidity information) via the wireless transmitting means 400 from the sensor units 410a to 410n, and computes a weight average based on the sensor information and weight values that are pre-stored in the storing means and that correspond to the sensor units. Using the computed value as a control value, the controlling means 311 controls an air conditioning unit.

A method A communication section 200 in an optical communication interface 100 communicates with outdoor units 300a and 300b and indoor units 310a and 310b using a communication method A. A central management controller 600 communicates with the optical communication interface 100 using the same communication method A and manages the outdoor units 300a and 300b and the indoor units 310a and 310b according to the communication method A. A method B communication section 205b in a communication method B indoor unit 311 of a different manufacturer communicates with a method B communication section 205c in a communication method B outdoor unit 301 using a communication method B different from the communication method A. The optical communication interface 100 of the communication method A and the indoor unit 311 of the communication method B exchange information by optical communication with each other using an optical communication section 202a and an optical communication section 202b. The central management remote controller 600 centrally controls a plurality of equipment items, for example, performing an energy-saving control by changing set temperatures of an air conditioner using the optical communication interface 100.
摘要:
An owner concludes with a facility maintenance company a contract for maintenance of electric facilities and an operation control monitor device installed in a building of the owner. The electric facility manufacturer gives the company permission to access the device from a terminal through the Internet as a communication network. The company receives continuous monitor data items of the electric facilities collected by the device. The manufacturer accesses the device from a terminal through the network and also receives the continuous monitor data items of the electric facilities.
