Off-peak electricity energy-storage combined energy supply station coupling seawater source heat pump and gas-fired boiler

Abstract

The invention discloses an off-peak electricity energy-storage combined energy supply station coupling a seawater source heat pump and a gas-fired boiler. The off-peak electricity energy-storage combined energy supply station coupling the seawater source heat pump and the gas-fired boiler comprises a seawater taking and returning system, the water source heat pump unit, the condensing type gas-fired boiler, an energy-releasing heat exchanger and an energy-storage water tank. The seawater taking and returning system comprises a seawater plate heat exchanger, a grid water taking pond and a seawater pump; and the water source heat pump unit is connected with the seawater plate heat exchanger. According to the off-peak electricity energy-storage combined energy supply station coupling the seawater source heat pump and the gas-fired boiler provided by the invention, new energy is used to replace centralized heating / cooling of a coal-fired boiler implementation area, so that the aims of energy conversation and emission reduction are achieved, and meanwhile, the operating cost of the new energy is lower than the operating cost of traditional energy.

Description

technical field [0001] The invention relates to the field of regional centralized cooling / heating supply, in particular to a low-valley electric energy storage combined energy supply station coupled with a seawater source heat pump and a gas boiler, which combines with the gas boiler to perform peak shaving during the heating period. Background technique [0002] At present, traditional municipal heating uses coal-fired boilers, but the biggest disadvantage of coal-fired boilers is that they are not environmentally friendly, have a large sulfur content, and the emissions after combustion will cause serious air pollution, and hoarding requires a lot of space , and more dust. With the rapid economic development in China, especially in coastal cities, great achievements have been made in various constructions, but considerable resources and environmental costs have also been paid. The contradiction between economic development and resources and environment has become increasing...
