Seasonal low-level energy surface water cool storage air-conditioning method and device

Abstract

The invention relates to a seasonal low-level energy surface water cool storage air-conditioning method and device. The method comprises the following steps: collecting low-level energy water in cool seasons, precipitating, filtering, storing a small part under the condition of heat insulation, using a large part to make ice, chilling; and melting ice blocks in hot seasons to obtain chilled water, and using ice blocks and chilled water to perform heat exchange with an air conditioner. The device of the invention comprise a settlement tank, a filter tank, a heat insulation water storage tank and a lift pump house which are connected with a pump in turn through a pipeline and also comprise an ice machine set, a heat insulation refrigeration house, an ice-melting pool and a cold water tank, wherein the output end of the lift pump house is connected with the input ends of the ice machine set and the ice-melting pool respectively, the output end of the ice-melting pool is connected with the input end of the cold water tank, return coil pipes of a heat exchanger of the air conditioner are arranged in the ice-melting pool and the cold water tank, and the air conditioner can normally operate by reducing the temperature of the air conditioner return water. The method and device of the invention utilize seasonal temperature difference to store cold energy in winter low-level energy water to use in summer, thus reducing the load of thermal power, lowering carbon dioxide release and achieving obvious effect of energy-saving and emission-reduction.

Description

technical field [0001] The invention relates to a technology for comprehensive utilization of natural surface water resources such as rivers, lakes and seas, and specifically refers to a seasonal low-energy surface water cold storage air-conditioning method and equipment thereof. Background technique [0002] A system that stores cold / heat in a certain medium or material and releases it in another period of time is called an energy storage system. When cold / heat is stored in a certain medium in the form of sensible heat or latent heat, and the air-conditioning system that can release cold / heat when needed is called a cold / heat storage air-conditioning system. Ice storage technology is a high-efficiency and energy-saving technology first developed abroad in the 1980s. In 1979, the United States took the lead in compiling and publishing the "Guidelines for Cooling Buildings During Off-Peak Periods", and then began to promote the application of ice storage technology on a larg...

Problems solved by technology

Although this ice storage technology has the advantage of reducing the power consumption of chillers, boilers, fans and water pumps, and thereby reducing the electrical load during the peak period of electricity consumption, it still has the following defects: First, the ice storage technology used The medium is common domestic water in the current season, and the demand is very huge. According to the valuation of 1 to 2 yuan per ton of domestic water, its use cost remains high, which brings a heavy burden to the enterprise; second, this kind of ice storage The technology only uses the time-of-use billing rules of power supply companies to save part of the electricity cost, but it does not actually save electricity consumption. This is still far from the established policy requirements of the country's energy conservation and environmental protection.

Our country is rich in surface water resources, especially in the southern part of our country, but the utilization methods of these free surface water resources are relatively single, and the utilization rate is not high, especially the stored potential has not been brought into play
