Abstract
Based on the characteristics of hot water supply in bathroom, this article proposes a new hybrid energy hot water supply system. The programmable logic controller(PLC) as the master controller was adopted in this system, which could automatically detect and storage main thermal physical of the system, such as temperature, water level, solar radiation intensity, power consumption and so on. The active thermal utilization technology of solar energy, air-source heat pump technology, solar energy intensive natural ventilation technology and low temperature hot water floor radiant heating technology were organically integrated in this system, which has the advantages of energy conservation and environment protection, high automation, safe and reliable operation, etc. At the same time, it can make good use of electric power cost between on-peak and off-peak, and promote the optimal allocation of power resources and reduce the cost, which can achieve the goal of intelligent control and energy saving.
Highlights
With the continuous improvement of living standards, people's demand for quality is getting higher and higher, in order to relax and shape a good personal image, bath has become an indispensable activity in people's lives
The solar hot water supply technology is becoming more and more mature, has been widely used, but it is highly dependent on environmental conditions, the stability and reliability is poor, often need to combine with the stable heat source
The traditional bathroom heating system usually use gas or coal boiler as heat source, rely on the installed on the wall of the indoor heating radiator heating device
Summary
With the continuous improvement of living standards, people's demand for quality is getting higher and higher, in order to relax and shape a good personal image, bath has become an indispensable activity in people's lives. The solar hot water supply technology is becoming more and more mature, has been widely used, but it is highly dependent on environmental conditions, the stability and reliability is poor, often need to combine with the stable heat source. Most of the traditional bathroom adopt simple natural ventilation technology and its effect is poor, lead to indoor air pollution, hypoxia and make people feel serious discomfort. Low-temperature floor radiant heating system is a new heating type, it takes the whole ground as a heat sink, when convective heat transfered between floor and indoor air, people can have a comfortable feeling- feet warm head cool, it can use the low-grade heat source as heat source, it is a kind of ideal heating system to reduce the energy consumption and improve the comfort of the building. In part 1, we introduce the composition of hybrid energy-saving bathroom system; In part 2 we introduce the working principle and performance analysis of the system; In part 3 we introduce the innovation and application in other fields
