Description
Technical field
The present invention relates to a kind of suitable for south based on the cold thermally equilibrated ground-source heat pump system using accumulation of energy, belongs to building
Field of air conditioning.
Background technique
With the development of social productive forces, people's lives level is gradually increased, requirement of the living environment to air-conditioning technical
Also it increases accordingly, for air-conditioning device while meeting design requirement, indoor comfort, the requirement to its energy-saving and environmental protection is higher.
Earth source heat pump is the technology of a kind of use cleaning using soil as Cooling and Heat Source, renewable energy.Earth source heat pump system
System is in summer constantly from indoor absorption heat dissipation to underground;Winter extracts the heat in soil constantly then to realize indoor confession
It is warm.Regional in south China, refrigeration duty, which is greater than thermic load, causes summer to be emitted into the heat that the heat of underground is absorbed greater than winter
Amount, unit is run for a long time then can form " hot stack " in underground, be gradually increasing underground zone of constant temperature temperature, earth source heat pump
Cooling efficiency deteriorates year by year, influences the normal use of unit.Therefore, in the design process of earth source heat pump, it need to guarantee the system summer
Both heats that season extracts from soil to the heat dissipation capacity of underground and winter balance.
To alleviate hot stack phenomenon, general there are three types of approach: first is that using cooling tower auxiliary heat dissipation, heat that summer is had more
Amount is discharged by cooling tower, it is ensured that summer in winter thermal balance;Second is that taking heat recovery technology, converts waste heat to and produce life
Apply flexibly water;Third is that buried guard system is designed according to winter heat absorption load, and small-sized water cooler is taken in cooling supply part when design
Assist cooling supply.As the heat that summer has more is drained into atmospheric environment by cooling tower by patent 201210103729.2, then assist with
It mends cool equipment and achievees the purpose that soil whole year load balance.This patent defect is to have more cooling tower and refrigeration unit, lead
Complex system is caused, reduces reliability, and result in high operation energy consumption.Underground pipe is divided into A by patent 201510755458.2
Area and the area B, are used alternatingly, and when system is in partial load condition, only use the area A as system Cooling and Heat Source, the area B is then connected to
Natural heat-exchange circulation, draw heat/cooling capacity are sent into underground pipe and are stored, use in season in next heating season/refrigeration.This patent
Defect is then to guarantee underground pipe subregion into that the underground pipe in single region can satisfy cold heat amount, ground required for winter in summer
Pipe laying quantity is twice of normal single area underground pipe quantity, and initial cost is high, system complex.
The present invention using earth source heat pump as Air Conditioning System be applied to air-conditioning system, phase-change heat-exchanger by summer without
Method is got up by the accumulation of heat that soil balances, and domestic water and heating water are produced in transition season and winter.Both it alleviated
Earth source heat pump " hot stack " problem, while originally extra heat utilization being got up again, realize the efficient utilization of the energy.
