Desktop type self-water-supply heat exchanger performance testing device

Abstract

The invention provides a desktop type self-water-supply heat exchanger performance testing device based on a semiconductor heat pump. The semiconductor heat pump technology is utilized, the size is small, control is flexible, and the desktop system requirement is met; energy conservation is realized, especially when cold water and hot water are supplied at the same time, energy compensation is achieved, and cold and hot source energy is recycled; periodical water supply is realized, water supply and sewerage are not needed, the experiment is convenient and flexible, and the device is not limited by the positions of water supply and sewerage pipes; a heat exchanger type expansion water tank is adopted, a large-size cold and hot water tank is abandoned, the structure is compact, mixed cold and hot compensation heat exchange of cold and hot water is achieved, the environment heat exchange load is reduced, and water supplementing, pressure fixing and system gas discharging or excessive water containing are achieved. The device is flexible, convenient, compact in structure, water-saving, environment-friendly, energy-saving, capable of achieving thermal performance and resistance characteristics of a liquid-liquid heat exchanger, and widely suitable for experiment teaching and testing requirements of the heat exchanger.

Description

technical field [0001] The invention relates to a desktop type self-supply water heat exchanger performance test device, in particular to a desktop type self-supply water heat exchanger performance test experimental device based on a semiconductor heat pump. Background technique [0002] At present, the shortage of laboratory space and aging equipment are common phenomena in colleges and universities. Even if the laboratory is recycled and the public arrangement is very crowded, the relevant water and sewage facilities are unsustainable, which has become a luxury. [0003] Conventional heat exchanger performance testing devices require the use of upper and lower water configurations or bulky water tanks, and the hot and cold water tanks are arranged separately. Tap water is often used as the cooling medium. After tap water is used, it is directly discharged into the sewer through pipelines, and a separate heating device is required. This method of operation has at least the ...
