Air source heat pump is mainly used in rural self built houses, old residential areas, villas and other fields to provide civil heating and hot water demand. How to select and install household heat pump, how to price and heating effect of air source heat pump? Through examples to show how to solve all the problems

Take lipanzhuang village villa in Haiyang town of Qinhuangdao City as an example

Project overview : building area 268 m2, heating area two hundred and twenty-eight M2, wall material twenty-four Wall, insulation five Cm thermal insulation, a total of two layers, the area of one layer is one hundred and sixty M2, two floors one hundred ㎡。 2015-2016 Outdoor temperature is coldest in annual heating season -20 C to -23 About ℃.  

solve the problem : solve the indoor heating temperature 18-23

Solution The second floor adopts the floor heating piece, one platform 10P Lipman air source heat pump air conditioning unit is not started, 2014-2015 The total operating electricity in heating season is 12000kw · h , average operating power 0.35kw · h/ The indoor temperature reaches the national standard twenty twenty-five ℃。 2015-2016 The total operating electricity in heating season is 14450kw · h Average operating cost 0.42kw · h/ The indoor temperature reaches the national standard twenty twenty-five ℃。
