Central air conditioning system global optimization energy-saving control method and device based on model

The invention provides a method for controlling a global optimization of energy saving for a central air conditioning system based on a model, comprising a control module, a multichannel data acquisition card and control card, a refrigerating unit data collector and a controller, a humidity sensor, a temperature sensor, a flow sensor, a watt transducer, a water pump frequency converter, a fan frequency converter, an RS232/RS485 conversion module and a RS485/RS232 conversion module. The whole system can be operated under the condition of most energy saving according to an operating condition of optimized energy saving of each energy consumption device acquired by calculation of a calculation module by taking energy consumption modules of a refrigerating unit, a water pump and a fan and an ARMA air conditioning load forecasting model. The invention thoroughly concerns an influence of the operating condition of each power device in the system to the energy consumption of the whole system, takes a control strategy based on a forecasted air conditioning load, and performs an online update for the energy consumption modules of key energy consumption devices in the system, thereby greatly improving an effect of optimization of energy saving for the central air conditioning system.

Disk drive with nonvolatile memory having multiple modes of operation

A hybrid disk drive, i.e., a disk drive with two types of permanent storage media (conventional disk media and nonvolatile memory, such as flash memory), uses its nonvolatile memory in operational modes other than the power-save or “standby” mode wherein the disks are spun down. In a first additional mode, called a “performance” mode, one or more blocks of write data are destaged from volatile memory (the disk drive's write cache) and written to the disk and simultaneously one or more data blocks of write data are destaged from the volatile memory and written to the nonvolatile memory. In a second additional mode, called a “harsh-environment” mode, the disk drive includes one or more environmental sensors, such as temperature and humidity sensors, and the nonvolatile memory temporarily replaces the disks as the permanent storage media. In a third additional mode, called a “write-inhibit” mode, the disk drive includes one or more write-inhibit detectors, such as a shock sensor for detecting disturbances and vibrations to the disk drive. In write-inhibit mode, if the write-inhibit signal is on then the write data is written from the volatile memory to the nonvolatile memory instead of to the disks.

Air conditioner with self-cleaning function and control method for air conditioner

The invention provides an air conditioner with a self-cleaning function and a control method for the air conditioner. An indoor unit of the air conditioner is equipped with an indoor unit fan, an indoor unit heat exchanger, a humidifying assembly and a humidity sensor, wherein the humidifying assembly is provided with a spray hole which is formed in the indoor unit and is positioned at the air inlet upstream of the indoor unit heat exchanger. The control method comprises the following steps of: receiving a trigger that the air conditioner starts a self-cleaning function; controlling the indoor unit heat exchanger to operate in an evaporator mode and closing the indoor unit fan; judging whether humidity, detected by the humidity sensor, of an indoor unit working environment is lower than a preset temperature threshold value or not, starting the humidifying assembly if the humidity is lower than the preset temperature threshold value, spraying out water mists through the spray hole, and improving frosting degree at the indoor unit heat exchanger; and after determining that the indoor unit heat exchanger reaches a set defrosting condition, controlling the indoor unit heat exchanger to defrost, and taking away attached pollutants by water formed by defrosting, thereby realizing self-cleaning of the indoor unit heat exchanger. According to the scheme adopted by the invention, the self-cleaning effect is obviously improved.
