Energy audit and air-conditioning
Previously, the building vitality utilization was studied without qualification of aerating and cooling framework sorts, which created vast dispersal of the vitality utilization of the same building sort. To study vitality utilization of office structures utilizing air-source heat pump, six office structures utilizing air-source heat pump as a part of Shanghai were examined through vitality review and field test. The vitality use power (EUI) per annum ran from 102 to 139 kWh/m2, with a normal estimation of 126 kWh/m2. The EUI scope of office structures utilizing air-source heat pump is much littler than the EUI of office structures as indicated by the writing. Taking into account field test of the aerating and cooling (A/C) framework, it was found that the present fundamental issue of A/C framework included deficient refrigeration limit of A/C framework, low A/C framework vitality productivity, and little icy water temperature distinction. Countermeasures were presented to take care of the issues, including ① retrofitting part of the present air-source heat pumps to water-cooled chilly water aeration and cooling systems, ② retrofitting present air-source heat pumps into new air-source heat pumps, and ④ pump variable recurrence remodel. The A/C burden is evaluated by Canister strategy. As indicated by the contextual analysis in this paper, the compensation back period are around two years for the main measure, five to seven years for the second measure, and 0.65–2 years for the third measure.
Down to earth application: For the most part, the vitality utilization overview gives an extensive variety of information. To some degree, it is brought on by the review strategy which does not take the aerating and cooling sort into thought. The work weights on the vitality utilization of office structures utilizing air-source heat pump. The outcome demonstrated that the vitality utilization was in a moderately little range, which will be more important to industry. Vitality sparing measures concerning aerating and cooling framework is concentrated on the premise of the overview.
