Which Heat Exchanger Will Be Used to Grow Marijuana

What kind of heat exchangers are used for growing marijuana

1. Air heat exchanger (fresh air / return air heat exchange)

Function: In the ventilation system, to realize the exchange of heat between indoor and outdoor air to reduce energy loss. For example, in winter, cold outdoor air is exchanged with warm indoor air to preheat the fresh air to reduce heating energy consumption; in summer, the indoor cold is recovered through heat exchange to reduce the air conditioning load.

Common types: plate heat exchanger, rotary heat exchanger, suitable for planting environments that require frequent ventilation and air exchange, balancing temperature and humidity with energy-saving needs.

2. Water - Air Heat Exchanger (Air Conditioning or Underfloor Heating System)

Function: To regulate the temperature of the growing environment through hot or cold water circulation. For example, in summer, cold water is used to exchange heat with air in fan coils to lower the indoor temperature; in winter, hot water is used to exchange heat with air in floor heating ducts or radiators to maintain a suitable temperature for growing (the suitable temperature for industrial marijuana is usually 20-30 degrees Celsius).

Common types: shell and tube heat exchanger (connected to the chiller or boiler), finned tube heat exchanger (fan coil core components). 3.

3. Heat exchanger for dehumidification system

Function: Industrial hemp cultivation is sensitive to humidity (usually needs to be controlled at 40-60%), and high humidity environments are prone to diseases. Dehumidifier through the evaporator (low-temperature heat exchanger) to make the water vapor in the air condensation, and then through the condenser (high-temperature heat exchanger) to recover part of the heat, to avoid excessive drop in ambient temperature.

Common types: small plate or cased heat exchangers, integrated in dehumidification equipment.
