Gas vent control is performed so that gas refrigerant is led from a receiver to the suction side of a compressor via a receiver gas vent pipe by opening a receiver gas vent valve. Upstream side expansion valve subcooling control is performed so that the opening of an upstream side expansion valve is changed such that the subcooling of refrigerant is set to target subcooling at the outlet of a radiator. Downstream side expansion valve suction wetting control is performed so that the opening of a downstream side expansion valve is changed such that refrigerant is in a wetting state and the dryness is set to target dryness at the outlet of an evaporator.Type: GrantFiled: December 16, 2013Date of Patent: March 19, 2019Assignee: Daikin Industries, Ltd.Inventors: Yoshiaki Yumoto, Yukako Kanazawa, Keitarou Hoshika, Junichi Shimoda

Patent number: 10234157Abstract: A management system and a management method according to the invention calculate, on the basis of collected weather information, an operation record of a device, a state value and an acceptable range set for an area where the device is installed, and power-suppression-time during which electric power is suppressed, change-time during which the state value of the area is changed in response to the power-suppression-time by operations of the device, generate, using the calculated change-time, a control-schedule for controlling the device, and control the device. This enables reduction of electric power usage with the state value set for the area where the device is installed kept within the range in accordance with the power-suppression-time.Type: GrantFiled: August 6, 2014Date of Patent: March 19, 2019Assignee: MITSUBISHI ELECTRIC CORPORATIONInventors: Fuyuki Sato, Kenjiro Miura, Masahito Matsushita

Patent number: 10234158Abstract: A controller controls a first air-conditioning system and a second air-conditioning system having separate refrigerant circuits, but arranged for conditioning a common space. The controller includes a multi-variable regulator to determine control signals for controlling operations of first components of the first and the second refrigerant circuits to reduce jointly and concurrently an environmental error between setpoint and measured values of environment in the common space. The controller also includes at least two single-variable regulators to receive operational errors between setpoint and measured values of an operation of a second component of the first and the second refrigerant circuits. The controller separately determines control signals for controlling the operation of different refrigerant circuits that reduce the operational errors.Type: GrantFiled: March 6, 2017Date of Patent: March 19, 2019Assignee: Mitsubishi Electric Research Laboratories, Inc.Inventors: Christopher R. Laughman, Hongtao Qiao, Daniel Burns, Scott A Bortoff
