Perception of the relationship between a comfort level and environmental data is facilitated, and appropriate management of air-conditioning equipment is enabled. A comfort level display apparatus has a preference storage unit to store a preference of a user regarding an air-conditioned environment, an attribute storage unit to store an attribute of the user, an environmental data value acquisition unit to acquire an environmental data value representing a condition in an air-conditioned space, a comfort level value generation unit to generate a comfort level value indicating comfort of the user in the air-conditioned space, based on the preference of the user stored the preference storage unit, the attribute of the user stored in the attribute storage unit, and the environmental data value of the air-conditioned space acquired by the environmental data value acquisition unit, a display data generation unit to generate display data by synthesizing the comfort level value of the user generated by the comfort level value generation unit and the environmental data value of the air-conditioned space acquired by the environmental data value acquisition unit, and a display unit to display the display data.

Comfort level display apparatus that generates correlation information between user comfort levels and temperature changes

There is provided air-conditioning control in a low power operation so as not to exceed a target demand power amount in a predetermined measurement period while preventing deterioration of comfortableness of a living space. There include a reducible-power-amount estimation unit configured to calculate, for each group, a reducible power amount by making indoor units perform, for each group, a shut-off operation for a minimum shut-off time in the first half of a demand time limit, and a reduced-power-amount determination unit configured to distribute, when a power consumption amount predicted by a power consumption amount prediction unit exceeds a target demand power amount after the first half of the demand time limit passes, the exceeding power amount to each zone, evenly distribute, in each zone, the distributed power amount to each group, and calculate, based on the reducible power amount of each group, a shut-off time of each group when each group performs the shut-off operation to reduce the distributed power amount.

Demand control device and computer readable medium

An air conditioner control system comprises air conditioners configured to condition an environment in a target space, an integrated controller configured to control the air conditioners based on control parameter data, sensor devices configured to measure the temperature of the target space and transmit measurement data, and wireless master devices configured to create control parameter data based on the measurement data. The wireless master devices each determine sleep times so that at least two sensor devices run out of battery charge around the same time according to the remaining charge amount of each of the sensor devices. The sensor devices each will be in the sleep mode in which power consumption is lower than in the normal mode according to the sleep time decided by the wireless master devices.
