Cold air and hot water combined supply system based on open absorption cycle

Abstract

The invention discloses a cold air and hot water combined supply system based on open absorption cycle. The cold air and hot water combined supply system comprises an open absorption unit, a damp airtreatment unit and a heat supply unit, wherein the open absorption unit comprises an open absorber, a solution-water heat exchanger, a regenerator, a condenser and a subcooler; the damp air treatmentunit comprises the open absorber and a dew point evaporative cooler which are connected in sequence through an air pipe; the water vapor generated by the regenerator enters the dew point evaporative cooler after passing through the condenser and the subcooler in turn; the heat supply unit comprises the open absorber, the solution-water heat exchanger, the subcooler and the condenser which are connected through a water pipe; and cold water is heated by the open absorber and then enters the condenser through the solution-water heat exchanger and the subcooler, and hot water heated by the condenser is fed into heat supply space. Under the condition of low energy consumption, the system can make full use of high humidity gas energy and simultaneously provide cold air and hot water to realizeenergy reuse.

Description

technical field [0001] The utility invention belongs to the technical field of energy utilization, and in particular relates to a combined cold and heat supply system based on an open absorption cycle. Background technique [0002] my country's total energy consumption ranks first in the world. Even if it is averaged to the per capita value, my country's per capita energy consumption has exceeded the world's average level. However, my country's energy utilization rate is only 33%, which is about 10% lower than that of developed countries. According to statistics, in my country, at least 50% of the industrial energy consumption accounting for more than 70% of the total energy consumption is converted into industrial waste heat with different carriers and different temperatures during the production process, which has not been fully utilized. If this part of industrial waste heat can be effectively recycled, energy utilization efficiency can be improved. [0003] The open-ty...
