摘要:
An air conditioning system (100) comprising air conditioners (10a, 10b ... ) has one or more than one installed function of multiple functions; and a mobile terminal (50) carried by a user of the air conditioners (10a, 10b, ...), and further has an air conditioning management program for management of the air conditioners (10a, 10b, ...). The air conditioners (10a, 10b, ...) store installed function information (18a), which is information classifying a multitude of functions with which the air conditioners (10a, 10b,...) are potentially provided into functions that are actually installed in the air conditioners (10a, 10b, ...) and functions that are not installed. Information intermediation devices (40, 20a, 20b ... ) carry out exchange of installed function information (18a) between the air conditioners (10a, 10b, ...) and the mobile terminal (50), using a communication network (80), and the air conditioning management program (54) of the mobile terminal reads out the installed function information (18a) via the information intermediation devices (40, 20a, 20b,...), and generates, in accordance with the installed function information (18a), an air conditioner management screen image displayed on a display (55) of the mobile terminal (50).

In the method for detecting the configuration of a ventilation system, the exhaust air valves in the premises are detected. The ventilation system comprises a control apparatus (122) and a first subsystem (100), which includes a first ventilation unit (102) with an exhaust fan (104). The first subsystem further comprises a first exhaust air duct (108) connected to the exhaust fan, the ends of the exhaust air duct having been led to the premises (120, 121, 220, 221) and an exhaust air valve (112, 212) having been installed into the ends. In the detection, the exhaust air valves are determined an individualizing identifier, the exhaust fan of the first ventilation unit is switched on, the exhaust air valves installed into the first exhaust air duct are adjusted to the first flow position, and reference pressure values are determined for these exhaust air valves by measuring pressure differences over said exhaust air valves. One exhaust air valve connected to the first exhaust air duct in the first premise is then adjusted to the second flow position, in which air flow through the valve is substantially bigger than in the first flow position, pressure differences are measured over the exhaust air valves in the first flow position and the measured pressure differences are compared with the reference pressure values of the said exhaust air valves. The closed exhaust air valves, the measured pressure difference of which deviates substantially from the reference pressure value, are determined as valves in the first premise and they are given the same premise value as the exhaust air valve in the second flow position. The identifiers of the exhaust air valves with the same premise data are transmitted to the control apparatus. The premise can be an apartment of a block of flats or a terraced house.

A data aggregation part 14 uses, as a data set, setting data for controlling an air-conditioning apparatus 31 and a refrigerating showcase 32, the amount of electricity consumed by the air-conditioning apparatus 31 and the refrigerating showcase 32 and operation data thereof, and environmental data containing outdoor temperatures, and classifies the data set for each outdoor temperature. An environmental condition-specific analyzer 15 obtains optimum setting data for accomplishing energy saving for each outdoor temperature, by using the data set for each outdoor temperature. The environmental condition-specific analyzer 15 also corrects the amount of electricity consumption of the data set on the basis of the number of people in a space counted by a people counter 35. A time zone-specific analyzer 16 obtains optimum setting data for accomplishing energy saving for each time zone by using the optimum setting data for each outdoor temperature.
摘要:
A method for assessing an efficiency of a chiller. The method includes: performing, using a processor of a computer system, an energy balance check on operational data of a chiller in a chiller group; selecting, using the processor and based on the energy balance check, a reference chiller from one or more other chillers in the chiller group, wherein an energy flow of the reference chiller has a best energy balance amongst the one or more other chillers; determining, using the processor and reference operational data from the reference chiller, the efficiency of the chiller; and performing, based on the determined efficiency of the chiller, an action with respect to a chiller plant containing the chiller. Other aspects are described and claimed.
摘要:
An air conditioner that performs an air conditioning operation in an indoor space includes a compressor (12) and a controller (33) that controls an operating frequency of the compressor (12) at a predetermined update interval in accordance with an air conditioning load in the indoor space. The controller (33) shortens the update interval when a first condition indicating that the air conditioning load is low and a second condition indicating that a performance of the compressor (12) to the air conditioning load is high are satisfied.
