DESCRIPTION

Dry Room For Lithium Battery R&D

1.1. Purification requirements of each section:

Dehumidification area	Area(㎡)	Height(m)	Volume(㎥)	Temperature(℃)	Dew point(℃)	Person
Dry room	18	2.1	37.8	25±3	≤-40	3

1.2 Site requirements

1. The user provides water, electricity and air source to the unit connection as required. The user is responsible for the primary power distribution to the distribution cabinet of the dehumidification unit, ceiling air conditioning unit, refrigeration unit and water pump. The tap water is connected to the make-up point of the equipment, and the pipeline (supply air, exhaust air, return air, chilled cooling water) is connected to the interface of the dehumidification air conditioning unit and the water chiller.

2. The user is responsible for the production of cement foundation of the equipment.

2. List of dehumidification and temperature control equipment:

2.1 list of regional equipment specifications

NO.	Equipment name	Supply air volume(m³/h)	Unit model	Qty.	Area used
AHU-1	Rotary dehumidifier unit	3700	TMAX-3700SCH	1	Drying room

3. Calculation basis for selection design:

3.1. Design parameters of fresh air for users in summer: in order to improve the stability of the system, the outdoor design parameters are taken as the parameters of bad working conditions, the dry bulb temperature is 35 ℃, the relative wet bulb temperature is 75%, and the absolute moisture content is 27g / kg;

3.2. System load: light labor intensity produces heat (80-100w/h. person); the comprehensive heat load of the enclosure structure is calculated at 60-110 w/m2 according to the system layout and indoor heat source, with a height correction factor of 2%, equipment The heat load is calculated by 10%-20% of the installed power according to the type;

3.3. Humidity production: when the temperature is 23℃, the humidity production of personnel with light labor intensity is (80-100g/h.person); the ventilation and humidity load of the air-conditioned room is calculated according to the air-conditioning room's 0.1-0.2 air exchange permeability; return air The moisture penetration load is calculated based on the return air volume 1%-3% of the ventilation penetration volume; the ventilation moisture load of the low-humidity dry room is calculated based on the moisture production volume of 2-5g/m2 in the air-conditioned room;

3.4. System air volume: fresh air volume (20-50m3/h. person) and maintaining positive pressure in the room require 5-10 Pa in the drying room; ensure the humidity gradient of the drying system.

4. Unit selection parameter table and system flow chart:
