- Title:
- Thermal Load Calculation of Domestic Hot Water and Analysis of Gas Water Heater Selection
- 摘要:
- 针对《建筑给水排水设计标准》（GB 50015—2019）中“当局部热水供应设备供给2个及2个以上用水器具同时使用时，宜采用带有贮热调节容积的热水器”的规定，通过对比燃气快速热水器参数与卫生器具热负荷的关系，分析燃气快速热水器在住宅生活热水供应中存在的问题。结果表明：市场上常见的产热水能力为8~16 L/min的燃气快速热水器仅能供一个卫生器具使用，一厨一卫、一厨两卫的住宅宜采用有贮热调节容积的热水器。
- Abstract:
- Standard for Design of Building Water Supply and Drainage (GB 50015-2019) stipulates that water heater with heat storage regulation volume shall be used when the local hot water supply equipment supplies two or more plumbing fixture for simultaneous use. The problems of gas instantaneous water heater in domestic hot water supply were analyzed by comparing the relationship between the parameters of the gas instantaneous water heater and the thermal load of the plumbing fixture. The gas instantaneous water heater with hot water producing capacity of 8-16 L/min that is common in the market could only supply to one plumbing fixture. It is suggested that the dwellings with a kitchen and a bathroom, a kitchen and two bathrooms should equip the water heater with heat storage regulation volume.
