Problems solved by technology
The energy-saving energy of the fan after the intelligent control transformation of the kitchen fume exhaust system can be measured and calculated by installing an electric meter. However, there is no calculation method for the energy-saving effect of the air-conditioning and heating system brought about by the energy-saving renovation of the kitchen fume exhaust system, especially for the air-conditioning and heating system. When no transformation is carried out, the energy saving of this part cannot be directly measured

Embodiment Construction
[0021] The present invention provides a method for calculating energy-saving energy based on the intelligent control of kitchen fume exhaust system after building energy-saving renovation, including the following steps:
[0022] S1. Calculate the reduced air-conditioning cooling capacity Q after the renovation of the kitchen exhaust system cooling and heating heat Q heating ;
[0023] S2. Calculate the cooling energy efficiency ratio η of the summer air-conditioning room supplied by the kitchen area cooling Compared with the energy efficiency ratio of winter heating system η heating ;
[0024] S3, according to formula E summer =Q cooling ·η cooling 0.3;E winter =Q heating ·η heating 1.2997, get the energy saving of air-conditioning and heating systems correspondingly saved due to the single energy-saving renovation measures, among them, 0.3 is the standard coal factor of electricity, the unit is kgce / kWh; 1.2997 is the standard coal factor of natural gas, the unit is ...

The invention provides a scientific, reasonable and effective energy-saving calculation method for saving energy consumption of air-conditioning and heating after intelligent control transformation of a cooking fume exhaust system. The method includes: (1) hourly data collection of the air supply volume of the kitchen fresh air unit before and after renovation; (2) calculating the enthalpy value after collecting the supply air temperature and relative humidity of the kitchen fresh air unit; (3) measuring and calculating the air conditioner supplied to the kitchen area (4) Calculate the reduced air-conditioning cooling capacity and heating heat supply due to the retrofit of the kitchen range hood; (5) Obtain the energy-saving energy of the air-conditioning and heating system that is correspondingly saved due to the single energy-saving retrofit measure. The present invention calculates the energy-saving effect in the form of saving the amount of standard coal, and provides reference for the energy-saving effect of the energy-saving renovation of the range hood in the kitchen area. System energy savings measurement.
Description
technical field [0001] The invention relates to a method for calculating energy saving, in particular to a method for calculating energy saving for intelligent control of a kitchen fume exhaust system after building energy saving renovation, and belongs to the technical field of energy saving for kitchen equipment. Background technique [0002] Building energy-saving renovation refers to the selection of reasonable and feasible energy-saving renovation schemes through comprehensive analysis from the aspects of technical reliability, operability and economy through on-site energy-saving diagnosis and the principle of energy-saving renovation judgment on the basis of ensuring indoor thermal comfort environment and technical measures to improve the energy efficiency of buildings and reduce energy consumption. Among them, the measurement and verification of energy-saving energy after renovation has always been the difficulty and key point of building energy-saving renovation. Ho...
