Thermal performance detection system and method for balcony wall-mounted solar water heater

Abstract

The invention discloses a thermal performance detection system for a balcony wall-mounted solar water heater and a detection method using the same. In the scheme, a circular pipeline is arranged on a water inlet pipe and a water outlet pipe which are connected with a solar water tank; water with rated temperature is provided for the water tank so as to perform tests by a water mixing method and awater discharge method, and the result has high reference value; and the tested hot water is provided for the heat utilizing equipment so as to save water and reduce the detection cost. Moreover, a bracket is used for simulating the installation state of a solar heat collector, ensuring high objectivity.

Description

technical field [0001] The invention relates to a thermal performance detection system of a balcony wall-mounted solar water heater and a detection method using the detection system. Background technique [0002] my country is rich in solar energy resources. With the rapid development of all-glass vacuum solar heat collectors with independent intellectual property rights, my country's solar thermal utilization is becoming more and more extensive. At present, it is the world's largest producer and user of solar water heaters. [0003] In the application of solar water heaters in my country, more than 70% to 80% are compact household solar water heating systems, that is, ordinary in-line solar water heaters installed on the roof. This product has the earliest development, the most mature technology, and the most widely used. However, with the development of the construction industry, there are more and more high-rise buildings everywhere, and the roof area available for insta...

Problems solved by technology

However, the system has a complex structure and many links, and the price paid to ensure the constant temperature requirements of the national standard is too high, resulting in the system including multi-directional constant temperature configurations

In addition, too many links also lead to more heat loss links, and there are more leakage points, which makes maintenance inconvenient.

In addition, recycled water can certainly save water, but the performance of the recycled water becomes worse. Compared with the test results, the cost of water is not very high. It would be a good idea to use the heated water for thermal utilization. s Choice
