Engineering Background and Project Overview
Water source heat pump systems are at the forefront of green industrial transformation. In Hebei Baoding Zhongda Foundry Workshop, these systems provide efficient and sustainable heating and cooling, ensuring optimal temperature control for precision machining processes.
The project aligns with national clean energy policies. It uses a water source heat pump as the main heating source. Surface-mounted fan coil units enhance temperature control. The system ensures energy efficiency and environmental friendliness.
System Design Ideas
The design focuses on water source heat pump technology. It ensures precise temperature control and low-carbon energy saving. CNC machine tools need stable temperatures for proper performance. High or low ambient temperatures affect equipment performance directly.
Engineers proposed a clear design strategy. They selected water source heat pumps driven by electricity. These pumps absorb natural heat, achieving 520%-780% thermal efficiency. Engineers chose Universal exposed fan coil units for uniform temperature distribution. They optimized energy use and abandoned coal or gas heating. This strategy reduces environmental pollution significantly.
Working principle of water source heat pump system
The water source heat pump uses circulating water to extract heat. It consumes little electricity to convert heat into high-temperature energy. The system then heats or cools the workshop efficiently.
Its operation works as follows:
The system extracts low-grade heat through circulating water. The compressor converts this low-temperature heat into high-temperature energy. The high-temperature energy heats or cools water. The fan coil releases this energy into the workshop.
This design ensures year-round efficient operation. It meets temperature requirements even during Hebei’s cold winters.
Cooling and heating load analysis
The engineer calculates cooling and heating loads based on Hebei’s climate and the workshop structure.
The unit cold load index reaches 110W/㎡, with a total demand of 1320kW. The unit heat load index reaches 100W/㎡, with a total demand of 1200kW.
The system’s water source heat pump provides a rated cooling capacity of ≥1320kW. It also delivers a heating capacity of ≥1200kW. This ensures year-round heating and cooling needs are fully met.
Advantages of environmental protection and running cost
The system reduces running costs significantly. During a 120-day heating season, running 8 hours daily, costs per square meter stay around $2.
The system achieves high energy savings and efficiency. It delivers thermal efficiency of 520%-780%. This saves over 30% compared to traditional heating.
It adopts environmentally friendly technology. The system avoids coal-fired and gas-fired heating. It reduces carbon emissions and aligns with green policies.
Some areas offer subsidies for water source heat pumps. These subsidies help enterprises lower investment pressure further.
Summary of system advantages
The system improves thermal efficiency and lowers operating costs significantly. It ensures safe and stable operation by separating water and electricity. This eliminates any risk of electricity leakage.
The system operates reliably year-round. It remains unaffected by extreme winter cold or summer heat. It contributes to environmental protection by emitting zero pollution. This helps enterprises achieve sustainable development goals.
Future Development and Market Prospects
With the in-depth promotion of clean energy policies, the application of water source heat pump systems in the industrial processing field is promising. By integrating environmentally friendly technologies and efficient operation modes, this kind of system reduces costs for enterprises and at the same time makes an important contribution to environmental protection.
