Novel efficient chilled water storage operation method

Abstract

The invention relates to an electromechanical installation technology, in particular to a novel efficient chilled water storage operation method. The electric charge can be effectively saved, the peak-valley power supply quantity of a power supply network is balanced, and the energy-saving effect can further be achieved; The novel efficient chilled water storage operation method comprises the steps that 1, the water temperature of cold accumulation is increased, specifically, the e steps that 1, the is increased, and the evaporation temperature of a refrigerating unit is increased; 2, the temperature difference of energy is increased, specifically, after the volume and the structural form of a cold accumulation water tank are determined, matching with a chilling unit and a refrigerating system is carried out, and primary refrigeration energy storage or secondary refrigeration energy storage is adopted; 3, medium-temperature water in a water storage pool is used as cooling water of the conventional chilling unit; and 4, comprehensive application with the comprehensive energy-saving technology of an air-conditioning chilling machine room is carried out, and the technologies specifically comprises a tail-end hydraulic balance technology, a full-variable-frequency speed regulation technology, a one-pump-to-multi-machine technology, an intelligent variable-flow cooling tower technology, a cooling pump comprehensive control technology, a near-wet-bulb technology, a bidirectional variable-flow technology and a modular control technology.

Description

technical field [0001] The invention relates to electromechanical installation technology, in particular to a novel high-efficiency water storage operation method. Background technique [0002] Cold storage is a line-saving and energy-saving technology. The refrigeration efficiency of cold storage at night is generally lower than that of conventional refrigeration. ;Using the energy storage cold capacity directly for the terminal equipment, the difference lies in the amount of stored energy and the size of the stored energy used for the terminal, there is no big difference in the operation mode. This operation mode utilizes the electricity price difference between peak and valley electricity, which can reduce the electricity cost, and can effectively use the off-peak electricity to reduce the loss of the power grid; but this operation mode cannot improve the operating efficiency of the refrigeration unit and increase the COP value of the refrigeration room; Energy technolog...
