YTE Experts Explain: How Freeze-Type Dehumidifiers Heat Air While Dehumidifying

At YTE, we understand the critical need for high-efficiency and high-performance air treatment solutions among our customers. Especially when it comes to freeze-type dehumidification technology, many users are curious about how this technology can effectively dehumidify while seemingly warming the expelled air. This article aims to delve into the workings of freeze-type dehumidifiers, focusing on how through intricate refrigerant and air circulation processes, they manage not only to control humidity but also to inadvertently provide a heating benefit.

The Working Principle of Refrigerant Cycle

The core of a freeze-type dehumidifier is based on an efficient refrigerant cycle process that includes four key steps: compression, condensation, expansion, and evaporation. This cycle is crucial for moisture removal from the air and also unexpectedly contributes to heating the environment.

  1. The Role of the Compressor: The compressor compresses the refrigerant into a high-temperature, high-pressure gas, initiating the refrigerant cycle and marking the beginning of the heating process.

  2. The Function of the Condenser: In the condenser, the high-temperature, high-pressure refrigerant gas releases heat to the surrounding air while condensing into a liquid. This release of heat is the primary reason for the rise in temperature of the air expelled from the unit.

  3. The Expansion Valve's Regulation: After passing through the expansion valve, the refrigerant experiences a sudden drop in pressure and temperature, turning into a low-temperature, low-pressure liquid, ready for the evaporation process.

  4. The Cooling Effect of the Evaporator: In the evaporator, the refrigerant absorbs heat from the air and evaporates, cooling the air and bringing it below the dew point, thereby dehumidifying it.

The Heating Effect of Air Circulation

The air circulation in freeze-type dehumidifiers also plays a vital role. Air is first dehumidified as it passes through the evaporator and then heats up as it passes through the condenser, absorbing heat released by the refrigerant. This process not only effectively removes moisture but also inadvertently heats the environment, offering a more comfortable living or working space.
