Technical Field

[0001] The utility model relates to the field of heat evaluation, in particular to an energy efficiency collection device for a deep well heat pump system. Background Art

[0002] Current deep well heat pump systems lack reasonable and effective means of energy efficiency assessment. Most sites are manually recording electricity meter data, heat meter data, and manual calculations. The data cannot be guaranteed to be real-time, and it is difficult to serve as a basis for energy efficiency analysis of deep well water source heat pump systems. Although there are some energy efficiency collection devices on the market, they are not developed for deep well water source heat pump systems, so they are inconvenient to install and use. For example, a centralized collection box has a large number of collection modules installed in one box, and a wired connection is used. On-site installation requires laying cables, which is difficult to install, resulting in cable waste after measurement. Often only the output heat and cold volume is measured, but not the water source heat and cold volume, so the efficiency of the equipment in the computer room cannot be accurately evaluated.
