摘要:
Apparatus for monitoring and analysing the performance of a heating and/or cooling system for a space within a building. The apparatus comprises a processing arrangement and an electronic memory, wherein the processing arrangement is configured to receive temperature signals representing temperature measurements from a temperature sensor within the space over a monitored period of time, to process the temperature signals so as to generate output data which attributes a proportion of the energy consumption of the heating and/or cooling system to a specified energy output, and to transmit the output data to the electronic memory for retrieval by a user. Corresponding monitoring and analysis methods are also described.
摘要:
Apparatus and methods for monitoring a hot water tank (10) of a hot water heating system, particularly with a view to minimising the energy consumed in supplying sufficient hot water. The apparatus comprises at least two tank temperature sensors (4, 5, 6) for sensing the temperature at at least two different tank heights and generating respective sensor signals in response to the sensed temperatures; a processing arrangement (22) configured to receive the tank sensor signals, determine therefrom a hot water level parameter value which is indicative of the proportion of the total volume of water in the tank which is above a predetermined temperature threshold, and output the hot water level parameter value; and an electronic memory (24) for receiving and storing the hot water level parameter value.
