在 此基础上， 给出了燃油低压热水锅炉的不确定度分析模型及 评定实例。
Then, a fuel-fired low-pressured hot-water boiler is employed as an example to illustrate the proposed method.
随着环境的变化，热泵热水机将出现冬季结霜，夏季出现低压压力过高的现象。
With the change of environmental temperature, the air sourced heat pump water heater will frost in winter and the low pressure will be too high in summer.
