How to design hotel HVAC

Design content:

(1) Collection of meteorological data.

(2) Heat and moisture load calculation

Calculate the air-conditioning heat and moisture load of the designed building under the most unfavorable conditions.

(3) Determine the best air conditioning solution

(4) Calculation of air supply volume and air flow organization

1. Based on the calculated air conditioning heat and humidity loads and Use the air supply temperature difference to determine the air supply status and air volume in winter and summer

2. Calculate and determine the minimum fresh air volume according to the working environment requirements of the designed building

3. According to the air conditioning method And calculate the supply and return air volume, determine the form of the supply and return air vents, arrange the supply and return air vents, and design the air flow organization.

(5) Air-conditioning water and air system design

1. Arrange air-conditioning air ducts, conduct hydraulic calculations of the air duct system, and determine pipe diameter, resistance, etc.

2. Arrange air-conditioning water pipelines, conduct hydraulic calculations of the water pipeline system, and determine pipe diameter, resistance, etc.

(6) Design and selection of main air-conditioning equipment

1. According to the air-conditioning System air treatment plan, combined with i-d diagram, carry out air conditioning equipment selection design calculation

2. Determine the capacity and air supply volume of the air treatment equipment, determine the structural form of the air treatment equipment and its thermal Industrial parameters

3. Determine the flow rate, wind pressure and model of the fan based on the hydraulic calculation of the air duct system.

(7) Ventilation, smoke prevention and exhaust system design

1. Determine the ventilation plan, calculate the required ventilation volume of the system, and pre-select the fan

2. Layout Ventilation system pipes and equipment, calculate pipeline resistance, determine pipe diameter, and select fan model

3. Determine the location of the smoke prevention and exhaust system, select the smoke prevention and exhaust method, and carry out smoke prevention and exhaust. design.
