Energy-saving and environment-friendly ground source central air-conditioning system

Abstract

The invention belongs to the field of air-conditioning systems and particularly relates to an energy-saving and environment-friendly ground source central air-conditioning system. A semiconductor refrigeration system and a high-frequency heating body are arranged in an energy-storing and heat-insulating box, and the energy-storing and heat-insulating box can supplement energy when the terrestrial heat is insufficient. Meanwhile, a water return system enables recycled water to flow into a work system or a recharge well according to different energy conversation requirements of the system, and therefore the system is better in energy conversation effect.

Description

technical field [0001] The invention belongs to the field of air-conditioning systems, in particular to an energy-saving and environment-friendly ground source central air-conditioning system. Background technique [0002] There are some significant disadvantages in the current ground source heat pump central air conditioners. First, it occupies a large area, requires a large investment, and has high operating costs, as well as very high maintenance costs. The second is that the efficiency of heat pump units is low in cold regions, especially in the extreme cold regions of the north. The third is that the heating-up time process is relatively long. In some small central air conditioners, there is still defrosting and ice-thawing time, and the heating will be interrupted during operation, which makes the human body feel uncomfortable. [0003] The Chinese invention patent "A Ground Source Heat Pump Energy Storage Central Air Conditioning System" (patent application number: ...

AI Technical Summary

Problems solved by technology

First, it occupies a large area, requires a large investment, and has high operating costs, and the maintenance cost is also very high.

Second, the efficiency of heat pump units is low in cold regions, especially in the extreme cold regions of the north.

The third is that the heating time process is too long. In some small central air conditioners, there is still a time for defrosting and defrosting. The heating will be interrupted during operation, which makes the human body feel uncomfortable.

However, the structure of this patent is still complicated, and equipment needs to be installed underground, which requires a large investment. Moreover, this patent uses a single cycle of high-pressure gas, and the energy-saving effect can be further optimized.
