Abstract

This design is designed for the air conditioning system of a comprehensive ward building of a Chinese medicine hospital in Nanjing. The design includes: calculation of heat and cold load; determination of design plan; design and hydraulic calculation of air duct system and water system; design of refrigeration room; air Selection of processing equipment; selection of cold and heat sources and economic analysis; insulation of pipelines; design of smoke control.

The design divides the whole system into two parts. The ward, the office and the operating room all adopt the fan coil and the independent fresh air air-conditioning system. The fresh air is treated to the indoor air devaluation and does not bear the indoor load. Choose the appropriate air supply method and determine the size of the air supply. The machine room is located in the independent refrigeration room of the basement. The refrigeration unit uses one screw-type chiller, three chilled water pumps and three cooling water pumps.

This design is to provide a comfortable environment for doctors and patients, and to reduce the energy consumption of air-conditioning. The theory is linked with the reality to achieve the comfort, economy, efficiency and energy-saving of the air-conditioning system.

Keywords: hot and cold load, chiller, fan coil, fresh air system
