热泵采暖是替代北方农村燃煤供暖的一种主要途径,普通热泵在环境温度较低时容易出现可靠性、舒适性差等问题,用于北方采暖具有一定局限性。使用双级压缩变频增焓技术的空气源热泵很好地解决了低温制热可靠性和舒适性的问题,不仅可以提高制热量,还可以节能,在北方农村选取用户进行示范取得良好效果,验证使用双级压缩变频增焓技术的空气源热泵在北方冬季采暖的可行性与经济性。
Heat pump heating is a major alternative to coal-fired heating in the northern rural areas. Ordinary heat pumps are prone to reliability and poor comfort when the ambient temperature is low, and have some limitations for heating in the north. The air source heat pump using double-stage compression frequency conversion enthalpy technology solves the problem of reliability and comfort of low-temperature heating well, not only can increase the heating capacity, but also can save energy, select users in the northern rural areas to obtain good results, verify Feasibility and Economy of Using Air Source Heat Pump with Two Stage Compression Frequency Conversion Increment Enthalpy Technology for Northern Heating in Winter.
