Can circulating cooling water be used for heating in the factory area

2009-11-08View Original

Thread Content

It involves a project in which the outlet temperature of the cooling circulating water is 45–50 degrees, and the volume of circulating water is very large. Can this type of circulating water be used for heating buildings in winter? What are the requirements for heating to be possible? Thank you!

Ensure that the cooling water is not contaminated and is harmless to the body.

According to the information provided by the poster, your factory’s cooling circulating water can be used for enterprise heating. I am not aware of the location where the poster is situated; if it is in a northern region, the outlet temperature of the cooling circulating water is 45–50 degrees, which is not sufficient to meet the requirements. In such cases, peak heating can be applied before the water is sent to the users. For operational safety, a secondary heat exchange unit should be installed in between; this unit uses cooling circulating water to heat the heating water, which then flows into the users’ radiators to carry out the heating task.

Sure. But the temperature is a bit low. When transported in this way, heat transfer is minimal, and the water pump consumes a lot of electricity. Judge whether it is cost-effective based on the actual situation. 1# hhxxbb

The results won’t be good. It’s better to keep the cooling water circulating.

It’s possible; using a water-based air conditioner will do. However, the increased resistance in the pipes and the impact of the water quality on such air conditioners can lead to higher maintenance and operating costs! It’s better to make a decision by taking energy consumption and maintenance costs into consideration as well!

No problem. I am gathering information on this topic.

Using cooled circulating water directly for heating is theoretically feasible, but it inevitably leads to the following disadvantages: 1. An increase in the volume of circulating water, which raises the cost of the equipment. (If the increased water volume has no impact on the process, it can be ignored.) 2. If it is used directly for heating, the temperature difference between the supply and return water will be very small; the water volume will be large, which increases the cost of piping materials. 3. What is the back pressure at the cooling water outlet? If the pressure is insufficient, considering installing a booster pump is necessary. 4. What method is used for heating during the maintenance of cooling towers? Here are a few suggestions for the original poster for your reference: 1. Install a swirl scrubber or an automatic dirt remover before the return water enters the tower. 2. Due to the low water supply temperature, it is recommended to use geothermal or air conditioning for heating. 3. Install a secondary heating device to increase the water supply temperature.

Heating can be used, but the operating conditions must be stable

It should work, right? It’s also a measure to save energy

First, it is necessary to determine the specific area where it will be used. Second, it is advisable to use a heat exchange station, with separate systems for heating circulation water and cooling water
