Problems solved by technology
However, district cooling networks (that is, networks of pipes and valves connecting several properties for cooling purposes) using water as a heat carrier are still rare
Instead, it is common practice to use electrical energy to run air conditioning systems, which is disadvantageous, at least from an environmental point of view

Embodiment Construction
[0029] The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which presently preferred embodiments of the invention are shown. However, this invention may be embodied in many different forms and should not be construed as limited to these embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and to fully convey to the skilled artisan convey the scope of the invention.
[0030] figure 1 A combined district heating and cooling system 100 is generally shown. The system 100 may utilize a heat pump for energy-efficient heating and / or cooling of buildings. As shown, system 100 includes a thermal energy loop and a plurality of buildings 114 . The plurality of buildings 114 may be thermally coupled to a thermal energy circuit, which may be arranged to circulate and store thermal energy in a heat transfer fluid flowing through the thermal energy circuit.

A method for identifying a deviation in a thermal energy circuit is presented. The method comprising: receiving (302) a first hot fluid flow measurement (f1) from a first hot fluid flow sensor (208) arranged in a hot fluid conduit (102); receiving (304) a first cold fluid flow measurement (r1) from a first cold fluid flow sensor (204) arranged in a cold fluid conduit (104); receiving (306) a second hot fluid flow measurement (f2) from a second hot fluid flow sensor (210) arranged in the hot fluid conduit (102) upstream the first hot fluid flow meter (208); receiving (308) a second cold fluid flow measurement (r2) from a second cold fluid flow sensor (206) arranged in the cold fluid conduit (104) downstream the first cold fluid flow sensor (204); receiving (310) a thermal device flow measurement (g) from a thermal device flow sensor (202) configured to measure a thermal device flow of a thermal device (106a) connected to the hot fluid conduit (102) downstream the first hot fluid flow sensor (208) and upstream the second hot fluid flow sensor (210), and to the cold fluid conduit (104) upstream the first cold fluid flow sensor (204) and downstream the second cold fluid flow sensor (206). The method further comprising upon (312) the first hot fluid flow measurement (f1) is different from the second hot fluid flow measurement (f2) and the thermal device flow measurement (g) in combination, generating (314) a first deviation signal indicating a deviation in the hot fluid conduit (102), or upon (316) the first cold fluid flow measurement (r1) is different from the second cold fluid flow measurement (r2) and the thermal device flow measurement (g) in combination, generating (318) a second deviation signal indicating a deviation in the cold fluid conduit (104).
Description
technical field [0001] The invention generally relates to a method for detecting deviations in a thermal energy circuit in a combined district heating and cooling system. Background technique [0002] Today, providing heating and hot water to homes and buildings via energy grids is common practice in many parts of the world. An example of such an energy network is a district heating network comprising a system of pipes and valves for distributing hot water to houses and buildings so that houses can be heated when required. Alternatively, according to another example, instead of using hot water to provide space heating, gas may be provided to houses and buildings via the system. A gas burner can be used to heat a home by utilizing gas, usually fossil fuel gas. In addition to space heating, hot water or gas can be used to prepare hot tap water. [0003] The downside is that the water used in traditional district heating systems can be very hot, sometimes close to 100 degree...
