摘　　要：本文讨论了北方寒冷地区(ⅡB)采暖常见的三种方式,指出热风采暖无论在何种外温下,都要求热媒温度高于45℃~48℃,因而,在冬季外温低到-15℃时,靠单级压缩的空气源热泵(R22)是不可行的。对于节能建筑,如既有建筑进行节能改造的(如达到75%节能),假如原有采暖系统中散热器面积不变,则供水温度不超过40℃,空气源热泵就可以用作它的供暖热源,对于辐射地板供暖不高于35℃的供水温度就很好了,所以,用普通空气源热泵就能够做它的热源。The paper discussed three kids of heating manners in cold climate （ II B）of our country ,points out that the outside temperature, hot air heating in any require heat medium temperature is higher than 45℃ -48℃, therefore, in the winter, low temperature 15C to-by single compressionair source heat pump （R22）is not feasible.for energy-efficient buildings, such as energy saving renovation of existing buildings （Such as 75% energy saving）, ifthe original heating system in the radiator area is constant, the water temperature is not more than 40 ℃, air source heat pump can be used as heating source, the radiant floor heating is not higher than 35% water temperature is very good, so use ordinary air sou rce heat pump heat will be able to do it.
