Land source heats up pump to bury ground heat exchanger to devise a method

From;  Author:Stand originally

Essentials of method of design of the heat exchanger that bury the ground summarizes association of hot pump of international land source (for reference)

Program of computation of the analysis of specific power consumption that system of groovy air conditioning involves, bear, system optimizes the content such as analysis of economy of choice, technology no longer tired narrate, but the design of system of land source hot pump must be mixed from system of subterranean heat exchange, computer room system consideration of terminal system whole, undertake reasonable optimize a design in the round.


Here emphasizes the design method that summarizes land source to heat up pump to bury ground heat exchanger:


1, the data is collected

The collection of data of 1.1. building foundation. Include the specific power consumption, bear, function, use schedule, usable area that bury a canal, all round the requirement of price of all sorts of water system conditions, the sources of energy, owner and demand.

1.2. geological perambulate, the collection of geological data. Basically be earthy with groundwater circumstance.

If 1.3. is purchased have restriction, still need to know land source heats up the parameter of pump aircrew, for instance the extreme offers backwater temperature.


2, the design that land source heats up pump to bury ground heat exchanger

2.1. is preliminary and affirmatory the form of a kind of heat exchanger that bury the ground.
- - perpendicular type or horizontal type (each have form of 5 kinds of above, combinative case

Analysis)
- - connect type or shunt-wound form (paralell connection is used more)

2.2. determines the position that bury a canal.

2.3. is in charge of material to be decided really.
- - material masters his all sorts of parameter (best PE, or PB even PVC)
- - dimension (SDR11 or 13, SCH)

2.4. is preliminary and affirmatory the temperature of subterranean soil (actual measurement or according to engineering experience) .

2.5. is preliminary those who decide subterranean soil is highest with lowermost temperature (check manual chart or according to engineering experience) .

2.6. is preliminary those who decide underground heats up pump aircrew is highest take water temperature with lowest (check manual chart and mix according to unit performance engineering experience) .

2.7. is preliminary and affirmatory the difference in temperature between subterranean soil and subterranean heat exchanger (check manual chart or according to engineering experience) .

The thermal resistance of conduit of 2.8. preliminary calculation and circular medium heat exchange (software computation, check manual hand to calculate, or according to engineering experience) .

The thermal resistance of conduit of 2.9. preliminary calculation and edaphic heat exchange (software computation, check manual chart, and according to engineering experience) .
