摘要
在空气源热泵热水系统设计中,贮热水箱容积的计算至关重要。介绍并分析了现行标准规程贮热水箱容积的计算公式,指出了公式运用时可能存在的问题。针对空气源热泵定时运行、24 h全日集中热水供应系统,根据热泵运行时间与用水高峰持续时段的覆盖关系,分情况分析并推导了贮热水箱容积的计算公式。在设计取值范围内,对上述推导公式计算的贮热水箱容积进行了分析。提出了贮热水箱容积在方案阶段的估算建议值。
The calculation for the volume of hot water storage tank is crucial in the design of an air-source heat pump hot water system.This article introduces and analyzes the calculation formulas for the volume of hot water storage tank in current standard regulations,and points out the possible problems in the application of the formulas.Based on the coverage relationship between the running time of the air-source heat pump and the duration of the water peak,the calculation formulas for the volume of hot water storage tank are analyzed and derived in a 24-hour centralized hot water supply system with the air-source heat pump running at a fixed time.Within the design value range,the volumes of hot water storage tank calculated by the above formulas are analyzed.An estimated value for the volume of hot water storage tank in the scheme stage is proposed.
