Difficulties in combining solar water heating system and high-rise residential appearance

With the shortage of urban land resources, in order to reduce the comprehensive development cost per unit of residential area on limited land, building high-rise residential buildings has become the first choice for developers. At present, the emergence of a large number of high-rise residential buildings also puts forward new requirements for the combination of
Development of solar water heating system and residential exterior combined design technology

Development of solar water heating system and residential exterior combined design technology

The solar water heating system includes solar collector, circulation system, control system, auxiliary energy system, heat storage system, support frame and other parts. So far, the combination of solar water heating systems and residential building exteriors in China has roughly gone through four stages of development. 1. Rural housing alone installation China’s solar water heating
Solar water heating system and building integrated design concept

Solar water heating system and building integrated design concept

At present, building energy consumption has accounted for about 30% of social energy consumption, of which the energy consumption required for domestic hot water preparation accounts for a large part. The application of solar water heating system in residential buildings can be used to prepare domestic hot water and reduce the use of conventional energy,
Connection of collectors and integrated design of solar water heating system

Connection of collectors and integrated design of solar water heating system

Connection of collector Since solar heating generally requires a collector of tens of square meters, and each collector module generally only has a few square meters, each solar collector system must be installed as a solar collector array. Different arrangements have an impact on the flow rate and heat exchange of each collector, and have
Forced circulation and DC solar water heating system

Forced circulation and DC solar water heating system

Forced circulation solar hot water system The forced-circulation solar hot water system is to install a water pump on the pipeline between the collector and the storage tank as the circulating power of the water in the system; at the same time, the useful energy of the collector is collected by heating the water and
Natural circulation solar water heating system

Natural circulation solar water heating system

Natural circulation solar water heating system refers to a system that uses solar energy to make the heat transfer working medium in the system naturally circulate and heat between the collector and the storage tank or between the collector and the heat exchanger. The power of the system circulation is the thermosiphon effect caused by
Classification of solar water heating systems

Classification of solar water heating systems

The international standard ISO9459 proposes a scientific classification method for solar water heating systems, which is classified according to the 7 characteristics of solar water heating systems. Each feature can be divided into 2~3 types, thus forming a rigorous solar hot water system classification system, as shown in Table 1. 1. The first feature represents
Classification of solar collectors

Classification of solar collectors

The device that absorbs solar radiation and transfers the generated heat energy to the heat transfer medium is called a solar collector, which is a key component of various solar water heating systems. The solar collectors currently used in China can be roughly divided into two categories: flat-plate solar collectors and evacuated tube solar collectors.

The development characteristics of solar photovoltaic power generation

The development characteristics of solar photovoltaic power generation

(1) China’s key technology mainly relies on foreign introduction, and its R&D and independent innovation capabilities are weak. The development of China’s photovoltaic industry basically relies on the introduction of foreign equipment and production lines, and then through digestion, absorption and re-innovation to improve localization capabilities. A number of key enterprises are paying more and
