Abstract: Introduction Ground Source Heat Pump Central air conditioning system works, ground source heat pump systems with combined radiation roof system design, soil type Heat exchanger Design. Focuses on ground source heat pump combined with the roof design of radiation, according to the geological structure conditions in Shanghai soil heat exchanger heat pump system. That the conditions of the geological structure of Shanghai is very suitable for the soil type heat exchanger in the form of ground source heat pump system.

0 Introduction Energy is the energy source, is the driving force of social development. Since the 20th century, due to world economic development and the constant pursuit of higher standards of living, energy consumption growth rate far exceeded the population growth. In our buildings to improve energy efficiency, its potential is huge. Building energy efficiency is a shortage of energy conflict mitigation, improvement of the people living and working conditions and reduce environmental pollution and promote sustainable economic development in a most direct and inexpensive basic measures of economic reform is a necessary component. Building and HVAC system design and operation of the process should be based on comfort as the goal, rather than consider the indoor temperature to ensure comfort in the premise of improving the dynamic performance of equipment and reduce peak load. This can be done to achieve greater energy efficiency. In this paper, ground source heat pump and floor radiant cooling technology used in combination.
1, ground source heat pump system, working principle and characteristics
The composition of ground source heat pump system
Ground source heat pump system consists of ground source heat pump, soil-type heat exchanger, expansion tank, circulating pump, indoor Air hose , Water pipes etc. (see Figure 1). Ground source heat pump water? Water and water? Air two types. Ground source heat pump and Air Source Heat Pump No different is the host on the outside. Ground source heat pump to be lifted in the bathroom ceiling, the storage room, basement or other shelter indoors. Soil heat exchanger is a high-density plastic pipe.

Into a closed loop. Cycle medium water or an aqueous solution added with antifreeze. System in Summer, through the underground heat exchange in the medium of circulation, the ground source heat pump units Condenser Heat release distributed to the soil. Winter time in the ground heat exchange tubes in the medium absorb heat from the soil and pass it to ground source heat pump units Evaporator (See Figure 2). As the two meters below the surface soil is basically free from the influence of atmospheric temperature, while maintaining a constant temperature year round, in winter soil temperature is higher than air temperature. Summer are far lower than the atmospheric temperature. Therefore, ground-source heat pump air source heat pump technology to overcome obstacles. Results from atmospheric air temperature, stable and reliable, and efficiency is greatly improved, more importantly, will not heat the surrounding environment and noise pollution. Is a national policy to encourage the use of a great form of air conditioning.

What is a high-pitched squealing sound in a natural gas heating system?
My natural gas heating system has a high-pitched whine. It doesn't always do this, but it's doing it often enough to make me think about bringing in a plumber. I'm thinking it might be the circulator pump since that's about the only moving parts in the system.
Any ideas? Thanks.
It could be the bearings on the blower motor as a signal that it is wearing out and needs to be replaced.
