The Research Of The Composite Air Conditioning System Of Ground Source Heat Pump And Heat And Humidity Independent Control

At present, energy is most shortage thing of the world, all the countries in the worldare promoting energy conservation and environmental protection. As the earth energylimited resources, the human are going to face a world lack of energy resources. In allhuman energy consumption, building energy consumption accounts for a large part, and inrecent years building energy consumption is thought of the most potential way of energysaving. In building energy saving, there are seneral technologies，such as wall insulationtechnology, the ground source heat pump technology, air source heat pump technology, andso on. In recent years, tsinghua university has put forward a new kind of air conditioningtreatment-heat and humidity independent control air conditioning, it processing indoor wetand heat waste separately, not only reduce the energy consumption of the air conditioningsystem but improve the indoor air quality.This article is put forward in this subject, use the heat and humidity independentcontrol air conditioning combined with ground source heat pump air conditioning system,processing indoor wet and heat waste separately. This subject through a complex buildingconstruction project, carry out the heat and humidity independent control air conditioningcombined with ground source heat pump air conditioning system research. Since heat andhumidity independent control air conditioning system processing wet and heat wasteseparately, the sensible heat load can come in the high temperature of cold source, desiccantbut need low temperature cold source to processing，so it requires the preparation of hightemperature and low temperature system of two kinds of cold water.Based on the analysis of building load of the complex building, calculate cold and heatload of the building throughout the year, heat and wet load calculated separately. Thenestablished the ground source heat pump as high temperature chiller+conventional waterchillers, ground source heat pump used to making low temperature cold water+air-cooledheat pump units two different ground source heat pump combined with heat and humidityindependent control air conditioning systems and one conventional refrigeration and airconditioning mode—ground source heat pump joint the cooling tower.Finally, through the theoretical calculation of the energy consumption of this therescheme, using the TRNSYS software to simulation the systems energy consumption andindoor amenity, to compare different scheme energy conservation and comfort, concludedoptimization design scheme of system combination.
