A high-efficiency and energy-saving hydroelectric air-conditioning system and its control method

Abstract

A high-efficiency and energy-saving hydroelectric air-conditioning system and its control method, including the water supply and return system of the deep reservoir of the hydropower station, and also include the fresh air unit, the cold and hot water unit, the terminal unit, the pipeline system and the control system; the pipeline system includes the thermal insulation water supply pipe One end of the thermal insulation water supply pipe is soaked in the deep reservoir water of the hydropower station's deep reservoir water supply and return system, the other end is connected to the fresh air unit, cold and hot water unit and the terminal unit, and one end of the drain pipe is connected to the fresh air unit, cold water The hot water unit and the terminal unit are connected. Through the improvement of the above-mentioned structure, the present invention abandons the unreasonable design of the air conditioner in the prior art, and uses the water in the deep reservoir of the hydropower station as a cold source for refrigeration or a heat source for heating in the air-conditioning system according to local conditions, and provides an advanced control method , has the characteristics of reasonable design, high efficiency and energy saving, high precision water temperature control, stable outlet water temperature, high use comfort, energy saving, and environmental pollution reduction.

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
