A desktop self-supply water heat exchanger performance testing device

Abstract

The present invention provides a desktop type self-supply water heat exchanger performance test experiment device based on semiconductor heat pump, which utilizes semiconductor heat pump technology, has small volume, flexible control, and adapts to the requirements of desktop systems; realizes energy saving, especially when hot and cold water are supplied at the same time. Compensation, recovery of energy from cold and heat sources; circulating water supply, no need for upper and lower water, convenient and flexible experiments, not limited by the position of upper and lower water pipes; heat exchanger type expansion tank is adopted, bulky cold and hot water tanks are discarded, and the structure is compact, realizing hot and cold water The mixed cold and heat compensation heat exchange reduces the heat exchange load of the environment, and at the same time realizes water replenishment, constant pressure, and removal of system gas or excess water; the flow rate is independently adjusted and is not affected by other factors, and each test condition is easy to achieve; considering downstream and countercurrent test conditions and its influence on energy recovery thermodynamic efficiency to maximize energy recovery; the invention is flexible and convenient, compact in structure, water-saving, environmentally friendly, and energy-saving, and can realize the thermal performance and thermal performance of liquid-liquid heat exchangers The resistance characteristic test is widely applicable to the experimental teaching and testing needs of heat exchangers.

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 ...
