Research Of Auxiliary Heat Pump Heating System

The buildings have huge heat load in winter with a quite high energyconsumption in severe cold area, the ground source heat pump heating system is anew tool of heating system,it is a geothermal ground source heat pumpheating recovery in poor condition,which use ground source heat pump heatingsystem as the construction of the heating auxiliary heat source, compatible withthe district heating network for heating. In order to improve the heating capacity ofheat pump system,we use solar seasonal heat storage of the program tosupplement the energy of the soil that heat pumps extracted from, thereby forincreasing the heat pump’s heating capacity and solving the problem of poor soiltemperature recovery and reduce the heat of the district The net heating powerwith the efficient use of solar renewable energy to save the consumption of fossilfuels, which provides a new way of building energy efficiency of the heating of thecold region.First we select device sample in the market and collect the operatingparameters of samples, and use Trnsys17software to form software model, weconstruct ground source heat pump of auxiliary heating systems. In cold area onbehalf of the city of Harbin, we simulate the joint heating system. The experimentsimulated the heating situation of the building in two types: heating mode basedmainly on heat pump and heating mode based mainly on heating network. The firsttype simulates the situation that the heating pump works when the heating load issmall and the two system work when the heating load is huge. The second typesimulates the situation that the heating network works when the heating load issmall and the two system work when the heating load is huge.For the mode of heating based mainly on heating pump, we simulated heatingin different regions of typical cities, they are Hailer, Shenyang and Beijing.The ground source heat pump of heating auxiliary systems is a new form ofheating system, We have finished energy analysis and economic analysis for thisnew system. This article fully proves the systems of energy saving, environmentalprotection and economy, which can be suitable for promotion in severe coldregions and cold regions.
