Evaporative condenser performance test method and system

Abstract

The invention discloses an evaporative condenser performance test method and a system thereof, and the test system mainly consists of the following parts: a test room, a main refrigeration system, an auxiliary air conditioning system, a room heat recovery system, an acquisition system and a control system. The test room is a closed space, a maintenance structure is subjected to heat preservation and damp-proof treatment, and a drainage system is arranged in the test room. According to the method, the heat transfer performance of the evaporative condenser under different environmental conditions can be tested, the heat transfer performance of the evaporative condenser under different working conditions is tested, the method has important guiding significance on engineering design and model selection, the heat recovery system is adopted to recover heat of a room and cold of the main refrigeration system, a high-capacity cooling system does not need to be additionally arranged in the test room to maintain the working condition, so that the construction cost and the operation cost of a laboratory can be greatly reduced.

Description

technical field [0001] The invention relates to the performance experiment field of refrigeration and heat exchangers, and in particular relates to a performance test method and system of an evaporative condenser. Background technique [0002] Due to the high energy consumption of refrigeration systems in industrial refrigeration and food cold chain industries, which is contrary to the national energy conservation and emission reduction policy and the "double carbon" goal, the heat dissipation effect of the condenser in the refrigeration system is directly related to the energy consumption of the refrigeration system. Studies have shown that, For every 1°C increase in the condensing temperature of the refrigeration system, the energy consumption of the refrigeration system will increase by 3%-4%. Condensers in this industry generally use evaporative condensers, and the heat transfer process of evaporative condensers involves complex heat and mass transfer processes, which ar...

AI Technical Summary

Problems solved by technology

Condensers in this industry generally use evaporative condensers, and the heat transfer process of evaporative condensers involves complex heat and mass transfer processes, which are difficult to calculate accurately. With the amplification factor, the equipment selection capacity is too large or the capacity is insufficient, resulting in material waste, cost increase and a series of engineering problems

Moreover, this equipment often has a large capacity, and its heat transfer performance is closely related to the ambient temperature and humidity conditions, and the industry standard does not give an accurate test plan. Domestic manufacturers rarely have laboratories for evaporative condensers. , so the parameters of domestic manufacturers refer to the parameters of foreign manufacturers, resulting in inaccurate sample data, so the industry selection is also relatively confusing

Moreover, the disadvantage of the evaporative condenser is that as the water evaporates, the ion concentration of the circulating water will increase, and dirt will form on the heat pipe wall and filler of the tube. Larger, inconvenient for engineering design
