The final design took about 3 weeks to get completed. Due to the client’s request for some modifications on the size and shape of the cabinet, it took more time compared to the initial schedule as some details had to be worked out. At the end of the project, an animation of the project was made and the final package was delivered to the client. The client was quite satisfied as all his requirements were met, and he made the following feedback:
“Thank you again for the excellent work… Both Mike and I are very pleased with the animation”
The project took about 3 weeks to get completed and was later checked with the client. The work suggested improvements on such components as the damper, counterweight, and the motor for both the bi-fold and quad-fold door. The design was then submitted to the client for the manufacturing.
The design was tested and it worked well. The client was quite satisfied with the work since it satisfied all its requirements.
Since the output temperature of the other heat pumps was considered to be 35℃ and the required temperature for the hot tub was to be 50℃, another heat pump with an output temperature of at least 60℃ was considered in the final plan.
After careful calculations and considering different options and scenarios, the design team found out the best solution for positioning the pipe under the ground at a distance of 1m. This solution succeeded to reach the value of 11.7 for the COP. This meant that it was possible to produce 11.7 times more heat with the same cost paid for the electricity consumption. In other words, by consuming 1 kW electricity, it was possible to produce 11 KW heat.
This project took about one month and according to the calculations, the design could lead to a considerable reduction in the electrical power consumption of the system and its cost and based on that, the client started its installation through a local company.
In order to understand and predict the function of the system, detailed calculations were made to find the behavior of the design at two steps of operation.
1. During the startup
2. During the normal operation
Calculations showed that during the startup stage, once the stable operation conditions were obtained, the dry rooms were ready for the next stage. Under normal operation, an increase of the RH was adjusted automatically by the PLC. PLC was programmed to gradually increase the rotation speed of blowers and based on the condition, it could adjust RH during the operation of the system.
Calculations proved that the design successfully met the requested requirements for 20ppm. Also, through proper choice of system’s different components, we managed to find a very cost-effective solution for making the design.
As requested by the client, the final solution featured all the given requirements and could be made just by using welding and drilling tools. The client made the designed gearbox and used it with a hydraulic motor. The final result was quite successful and he managed to use the final equipment was strong enough to roll a metal sheet with a thickness of 8 mm.
