摘要：

The　study　on　the　operating　characteristics　of　heat　pump　in　ventilation　heat　recovery　system　can　point　out　the　way　of　improvement　for　heat　pump　in　this　application.　An　experimental　platform　was　set　to　conduct　a　comprehensive　study　on　the　heat　pump　ventilation　heat　recovery　system　in　winter　conditions.　The　results　show　that　under　the　experimental　conditions,　the　system　pressure　ratio,　power　input　and　refrigerant　mass　flow　rate　decrease　with　the　decrease　of　outdoor　temperature;　the　recovered　heat,　temperature　effectiveness　and　COP　(coefficient　of　performance)　increase　with　the　decrease　of　outdoor　temperature.　Increasing　the　mass　flow　rate　of　the　system　can　be　an　effective　way　to　improve　the　performance　of　heat　pump　type　ventilation　heat　recovery　system.　©　2019　International　Institute　of　Refrigeration.　All　rights　reserved.
