An air conditioning system, a set temperature determining device determines a target temperature of water to be supplied to an indoor heat exchanger, based on [“target outflow temperature”=“current outflow temperature”+((“inlet and outlet temperature difference”/“indoor and outdoor temperature difference”)דset temperature difference”)]. The indoor and outdoor temperature difference is a difference between an indoor temperature and an outdoor temperature, the inlet and outlet temperature difference is a difference between temperatures of water at the inlet side and the outlet side of an intermediate heat exchanger, and the set temperature difference is a difference between an indoor temperature and a set temperature. A control device controls an outdoor unit in response to the target temperature determined by the set temperature determining device.

A method for controlling an environmental system may include defining a reference signal of an environmental variable in a greenhouse. The method may also include receiving renewable resource information related to the greenhouse. The method may further include receiving dynamic weather information of an environment external to the greenhouse. In addition, the method may include determining an optimization control scheme based on the reference signal, renewable resource information, and dynamic weather information. Further, the method may include regulating environmental conditions in the greenhouse according to the optimization control scheme.

An intercept device for HVAC controls that allows for overrides of local settings, either by onboard processing and storage, or by networked communication with on-premise or off-premise control mechanisms or cloud services. The existing thermostat may be mounted directly to the intercept device, or the intercept device may be located at any other location along the control line between the existing thermostat and the controlled equipment, allowing for retention of the original thermostats interface, controls, and aesthetics. The HVAC control intercept may also incorporate wired or wireless networking functions, and additional onboard controls and displays to allow for direct adjustment of the intercept device settings and operational mode.

A control device and method for preventing the start and stop of heat source machines from being frequently repeated. The control device determining whether or not basic conditions for decreasing the number of machines are satisfied when the number of currently operating machines is increased by one is determined if a current operational status satisfies basic conditions for increasing the number of machines, and one heat source machine is started if it is determined that the basic conditions for decreasing the number of machines are not satisfied, and determining whether or not the basic conditions for increasing the number of machines are satisfied when the number of currently operating machines is decreased by one are satisfied if a current operational status satisfies the basic conditions for decreasing the number of machines, and one heat source machine is stopped if it is determined that the basic conditions for increasing the number of machines are not satisfied.
