Abstract

The invention provides an efficient and energy-saving water-electricity air-conditioning system and a control method thereof. The efficient and energy-saving water-electricity air-conditioning system a hydropower station deep reservoir water supplying and returning system, a fresh air handling unit, a cold and hot water unit, a terminal unit, a pipeline system and a control system; the pipeline control system comprises a heat preserving water supplying pipe and a draining pipe; one end of the heat preserving water supplying pipe is soaked in water at a hydropower station deep reservoir of the hydropower station deep reservoir water supplying and returning system, and while the other end of the heat preserving water supplying pipe is connected with the fresh air handling unit, the cold and hot water unit and the terminal unit; one end of the draining pipe is connected with the fresh air handling unit, the cold and hot water unit and the terminal unit. According to the efficient and energy-saving water-electricity air-conditioning system with the improved structure above, the unreasonable design of air conditioners in the prior art is removed; the unique hydropower station deep reservoir of a hydropower station is used as a cold resource or refrigerating or a heat source for supplying heat of the air conditioning system according to the local conditions; in addition, the advanced control method is provided; the characteristics like reasonable design, high efficiency, energy conservation, high water temperature control precision, stable water outlet temperature, high comfort in use, energy conservation, and reduction of environmental pollution are brought.

Description

technical field [0001] The invention relates to a hydroelectric air-conditioning system, in particular to a high-efficiency and energy-saving hydroelectric air-conditioning system and a control method thereof. Background technique [0002] The hydropower station has a unique renewable resource—deep constant temperature reservoir water. The water temperature of the deep constant temperature reservoir water is between 7 and 25°C all year round (15-25°C in summer and 7-15°C in winter). The reservoir water at this temperature is very suitable It is used in the energy-saving application of air-conditioning system. If it is well applied, it can save a lot of electricity required for the operation of the HVAC system of the hydropower station. [0003] However, at present, most of the air-conditioning systems of hydropower stations still follow the traditional way of thinking and design. Like other buildings, they are designed as general air-conditioning systems, such as ordinary ai...

Problems solved by technology

[0003] However, at present, most of the air-conditioning systems of hydropower stations still follow the traditional way of thinking and design. Like other buildings, they are designed as general air-conditioning systems, such as ordinary air-cooled cold (hot) water units with terminals or ordinary water-cooled chillers with terminals. The central air-conditioning system has low operating efficiency and high energy consumption

The design of this system does not consider the unique environment and resources of the hydropower station at all, but only considers how to realize the air-conditioning system, and does not consider the issue of using the unique environment and resources to achieve air-conditioning energy saving, which leads to the inexhaustible resources of the hydropower station. Renewable resources are not used in favor of other cooling or heating methods that are not energy efficient

Ordinary air-conditioning systems with these cooling methods cannot meet the current national policy of "energy saving and emission reduction" and the requirements of building an energy-saving and environment-friendly society
