Dual-temperature heat transfer oil system

Fifty at low temperature? ? It’s way too low

This requires two sets of circulation pumps and systems.

This set includes one furnace and two pump systems (the flow rate can be controlled using a three-way valve in between), but it depends on how the high-temperature and low-temperature areas are allocated; it’s possible that this arrangement may not be suitable in such cases

I have designed an energy-efficient dual-temperature heat transfer oil heating system, for which I have obtained a **patent**. In systems that use heat transfer oil for heating or cooling, an important factor affecting thermal efficiency and economic costs is the switching between hot and cold oil during the process of temperature adjustment. When hot oil (or cold oil) is switched to cold oil (or hot oil), the hot oil (or cold oil) remaining in the jacket (or coils, semi-coils) of the reactor must be transferred to the cold oil (or hot oil) system, where it has to be cooled (or heated) to become cold oil (or hot oil). Each switch causes significant heat loss and cold loss. It is estimated that, for a reactor jacket with a capacity of 5 m3, the heat loss and cold loss associated with each switch-over are each around 60,000 kcal (equivalent to 70 kWh), which is undoubtedly a significant amount of loss. Of course, the specific amount depends on the volume of heat transfer oil in the jacket. How can we avoid this energy loss caused by the need to cool hot oil and then reheat cold oil? Creative ideas, excellent designs, and **patents enable you to solve problems easily, significantly reduce energy losses, and effectively cut production costs. Whether heat transfer oil is used for cooling or not, whether it’s the renovation of an existing system or the design of a new one, everything is so simple and easy. Low investment, high returns – why not give it a try? Guided by theory and based on practice, this technology has been implemented in large-scale projects. System design plans, control programs, and operating procedures can be provided.

Create two relatively independent systems: one for medium-temperature oil and another for high-temperature oil; in both cases, it is sufficient to provide oil at a constant pressure and temperature. I have been working on a project recently, involving 5 oil temperatures and 2 types of oils, covering low, medium, and high temperatures.

I am currently using three pumps for one cooling system. A set of heating. Due to some issues arising from the height difference during actual installation, the operation process becomes rather complicated; therefore, I was wondering if there are any similar cases that I could refer to

Could you send me some materials for reference? Thank you
