Question 1

What's the difference between cabinet AC and regular AC?

Accepted Answer

Cabinet AC is designed for industrial electrical cabinets with IP55 protection, wide temperature range (-40°C~+55°C), vibration resistance, and continuous duty operation. Regular home AC cannot meet these industrial requirements.

Question 2

What is a box-type transformer air conditioner? Why do transformer boxes need cooling?

Accepted Answer

A box-type transformer AC is designed for outdoor compact substations (European/American type transformer boxes, RMU boxes) where transformers and LV/HV equipment concentrate heat and can trip in summer. Haocheng HCK 3000–7500W cabinet AC units apply directly: IP55 dust/rain protection, -40~55°C range, wall/top mounting and 48V DC option — keeping transformers stable, extending equipment life and reducing outage losses.

Question 3

What's the difference between prefab cabin AC and cabinet AC?

Accepted Answer

A prefab cabin (integrated prefab substation, energy-storage cabin, containerized equipment room) is larger than a single cabinet and generates more concentrated heat, so it needs higher cooling capacity and more even airflow. Haocheng 5000W/7500W models suit prefab cabin cooling with top/side mounting and RS485 remote monitoring, providing precise climate control for primary/secondary devices and storage batteries in dusty, rainy, hot or cold environments.

Question 4

Are industrial air conditioners and cabinet air conditioners the same thing?

Accepted Answer

Industrial AC broadly covers refrigeration equipment for industrial environments (workshops, plants, equipment rooms). Cabinet AC is the sub-category focused on electrical enclosures: closed-loop compression cooling, IP55 protection, -40~55°C operation and long service life to protect electrical components. Haocheng's full cabinet AC series belongs to this high-end segment of industrial AC — for control panels, distribution cabinets, telecom cabinets and more.

Question 5

Besides vapor-compression cooling, what other ways cool electrical enclosures?

Accepted Answer

Common options: ①Filter fans — air exchange only, no real cooling, useless in high heat; ②Heat exchangers/heat pipes — passive, fail when the temperature difference is small; ③Thermoelectric (TEC) — no compressor, silent, but low capacity, for small cabinets only; ④Vapor-compression (cabinet AC) — active cooling with precise control, ideal for high heat loads and outdoor high-temperature sites. Haocheng uses compression cooling with smart control, balancing effect and energy use.

Question 6

How to choose the right cooling capacity?

Accepted Answer

Based on cabinet size, internal heat load, and ambient temperature. Generally: small cabinets (<1m³) → 3000W, medium (1-2m³) → 5000W, large (>2m³) → 7500W. Our engineers can provide precise sizing calculations.
