At CHINA SPEEDWAY, we provide tailored refrigeration products solutions for our clients. This month we have client buying cold room refrigeration unit, worked for a cold room project in very hot area. Bạn biết, the refrigeration unit used in normal area and super hot area has the very different design and configuration.
trong bài báo này, we will give you actual example how did we work in the super high ambient temperature cold room project and keep products fresh,frozen and durable, so as a reference for customers who has the similar condition.
Clients specifications
Clients need to accurately control the cold room temperture ( in a large temperature scope) to keep the goods fresh and durable, here are the details about this cold room project.
Country: Saudi Arabia
Nhiệt độ môi trường: Max 40~50°C ( Maximum 60 days for total in summer, each day 8 giờ)
Kích thước phòng lạnh: 7X4X3m (length x width x height)
Cold room application: Store foods ( fresh and frozen)
Nhiệt độ phòng lạnh: +5 ~-25°C (large temperature scope in this super high ambient temperature area)
Inverter condensing unit location: Outside the cold room
Cold room location: Resenditial area
Basic Solution
Inverter Condensing unit (outdoor unit): 7HP (Mã lực), 380V, 3phase 50Hz, R404 refrigerant. As max ambient temperature is 40~50°C, and last 60 days for maximum. So have to use bigger size condenser (use 9HP condenser but not 7HP condenser), also need a shelder to lower the temperature around the unit.

Trong khi đó, use inverter type condensing unit can save 50% electricity FOREVER, which can save lots of money for you.
Evaporator unit (đơn vị trong nhà): 8HP, 380V 3 phase 50Hz
Bảng điều khiển phòng lạnh: 150mm thickness PU sandwich panel with 0.35mm galvanized steel
cửa phòng lạnh: 150mm thickness PU sandwich panel with 10cm height threshold ( for better airtightness), cold room size–2.0×0.9m (height x width)
Backup power: Use 25kva diesel generator to avoid any sudden outage, which will damage your goods at all.

Specific Solution
1. Use large size condenser: Large condenser can increase the blow air volume
2. Prepare a shelter for condensing unit ( outdoor unit), which can reduce its surface temperature.

3. Use a window balance with 220V 50HZ to balance room inside and outside pressure.
4. Use sealant to get better airtightness, because easily loss cooling air will affect your cold room cooling performance.
5. Prepare a plastic air stripe curtain for the cold room door to avoid any cooling air to waste.
6. Use LED display screen board for inverter condensing unit to monitor the cold room temperature in real time.

7. Use one or two LED cold room light to keep the light clearly inside of the cold room.
