Solar water heating system for using summer residual heat to dehumidify solution

Abstract

The invention discloses a solar water heating system for using summer residual heat to dehumidify solution. A water outlet of a solar thermal collector is connected with a second check valve, a heat exchanging coil, a circulating pump, and a water inlet of the solar thermal collector sequentially; the water outlet of the solar thermal collector is connected with a first check valve, a high-temperature liquid coil of a first heat exchanger, a circulating pump, and the water inlet of the solar thermal collector sequentially; and the solution outlet of a solution regenerator is connected with a high-temperature solution coil of a second heat exchanger, a concentrated solution storage tank, a first solution circulating pump, a third heat exchanger, a dehumidifier, a dilute solution storage tank, a second solution circulating pump, the low-temperature solution coil of the second heat exchanger, a low-temperature liquid coil of the first heat exchanger, and a solution inlet of the solution regenerator sequentially. The solar water heating system realizes effective utilization of the residual heat of the summer solar water heating system, and greatly reduces energy loss of air conditioning systems.

Description

technical field [0001] The invention relates to the technical field of waste heat utilization, in particular to a solar water heating system in which waste heat in summer can be used for solution dehumidification. Background technique [0002] The solar water heating system technology is very mature, with good reliability and performance, and has multiple benefits such as economy, energy saving, and environmental protection. However, there is a common problem in solar water heating systems, that is, the imbalance between the heat supply and heat demand of the system. Especially in summer, the heat supply of the system is often much greater than the heat demand. According to the measurement data, the temperature of the water produced by the solar water heating system in summer can generally reach 65°C, and it can exceed 70°C when the sunshine is particularly good, while the water temperature is generally only required to be around 40°C, and the per capita water consumption is...

AI Technical Summary

Problems solved by technology

[0004] In summer, the air humidity is high, the temperature is high, and the energy consumption load of the air conditioner is large, but at the same time, the solar radiation is sufficient, and the heat supply of the solar water heating system is much greater than the heat demand
