Embodiment 1
[0049]In this embodiment, the selection of the optimal heat pump and its driving mode for a new heating scheme is used as an example to achieve the effect of economy and energy saving. A method for evaluating the energy-saving, economical and carbon-control benefits of heat pumps. Based on the energy consumption of the actual production plant process, different types of heat pump technologies are used to realize the recovery and utilization of low-temperature waste heat. The working parameters of each heat pump are obtained according to the principles of thermodynamics, and the equivalent electricity method is used. Unify the form of energy and establish an economic model of equipment, and then establish an average energy cost model to correlate energy, equipment investment and environmental expenditures. On this basis, different evaluation indicators are proposed to evaluate different types of heat pump technologies. The heat pump technology referred to in this paper refers to ...
Embodiment 2
[0124] In this embodiment, the analysis tower of a dry gas desulfurization device of an enterprise in Guangdong Province of China is taken as an example to illustrate Embodiment 1 in detail:
[0125] The first step is to obtain the local electricity price of 0.5¥ / kW. In order to meet the production requirements, it is necessary to supply 22.4MW of steam at 0.5MPa to the reboiler of the desorption tower. The steam at 107°C is produced at the top of the tower. The heat is 19.2MW, and the annual operation time is 8000h;
[0126] In the second step, according to the actual project, the heating capacity of the heat pump is determined to be 18.5MW. It is planned to use an open single-stage compression heat pump and a heating-up absorption heat pump to upgrade the low-temperature waste heat to supply the reboiler of the desorption tower. Among them, the compressor is driven by electricity, and the cooling and heating processes use cooling water at 7°C / 12°C and heat medium water at 95...
Embodiment 3
[0165] An evaluation device for evaluating heat pump energy saving, economic and carbon control benefits, the evaluation device is applied to the above method for evaluating heat pump energy saving, economical and carbon control benefits, including: a data acquisition module, a parameter calculation module, and a cost calculation module that are sequentially connected by communication , Evaluation module.
[0166] The data acquisition module is used to obtain various basic information of the original device and internal information of the heat pump;
[0167] The parameter calculation module is used to calculate the relevant heat pump working parameters according to the heat pump heating capacity specified by the low-temperature heat generation point of the original device by using the thermodynamic formula; convert the energy consumption of each component inside the heat pump into the corresponding equivalent power according to the equivalent power conversion coefficient;
