Central air-conditioning system with compound energy source

Abstract

The invention relates to a central air-conditioning system with a compound energy source, comprising a geothermal energy collecting device, a soil source heat pump unit and an air-conditioner tail-end air-feeding device. The central air-conditioning system with the compound energy source is characterized in that water outlets of the geothermal energy collecting device are respectively connected with water inlets of a heat pump unit heat exchanger and an indirect evaporation-cooling air processor; a water outlet of the heat pump unit heat exchanger is connected with a water inlet of the soil source heat pump unit; a water-returning port of the soil source heat pump unit and a water-returning port of the indirect evaporation-cooling air processor are connected with a water inlet of the geothermal energy collecting device; a new air port of the indirect evaporation-cooling air processor is connected with an indoor new air air-feeding device; and an exhaust port of the indirect evaporation-cooling air processor is connected with an air inlet of the heat pump unit. The central air-conditioning system realizes the effective heat-exchange function with long distance and high power, improves the heat-exchange efficiency, saves the energy source and reduces the operation expense, is beneficial to the health and can be widely applied to places including industrial and mining enterprises, offices, office buildings, residence communities and the like.

Description

technical field [0001] The invention belongs to the field of air conditioning systems, in particular to a composite energy central air conditioning system. Background technique [0002] At present, central air-conditioning systems using ground energy resources are increasingly being used in factories, office buildings and residential quarters. The existing ground source heat pump central air-conditioning system is mainly composed of three independent circulation devices, namely, the ground energy collection device composed of ordinary buried pipe heat exchangers, the energy lifting device composed of soil source heat pump units, and the air supply at the end of the air conditioner. device. The problems existing in the ground source heat pump central air conditioning system are: (1) The ground energy collection device uses an ordinary buried tube heat exchanger to exchange heat with the ground energy, and its heat exchange efficiency is low, which cannot meet the requirement...

Problems solved by technology

The problems existing in the ground source heat pump central air conditioning system are: (1) The ground energy collection device uses an ordinary buried tube heat exchanger to exchange heat with the ground energy, and its heat exchange efficiency is low, which cannot meet the requirements of high power and long-distance heat exchange. (2) The fresh air treatment in the heat pump unit requires the use of air supply equipment (fresh air unit) with a surface cooler, and the heat pump unit provides the cold source (heat source), resulting in waste of energy; (3) The air cannot be Purification and sterilization treatment, various inhalable particles and harmful gases in the air affect people's health
