LDAC with Heat Pump

  • 1


    By avoiding electric reheat, energy is conserved, cooling capacity is increased, and electrical hazards are eliminated.
  • 2

    DOAS technology

    Using Dedicated Outdoor Air Systems technology (DOAS), indoor sensible heat load can be removed by using higher temperature cold sources such as:
    - Surface water bodies
    - Direct or indirect evaporative cooling equipment
    - High temperature chillers
  • 3


    Cooling, dehumidification, and solution regeneration are driven by built-in heat pumps, thereby reducing electricity usage.

    Energy recovery

    Using heat recovery of return and exhaust air, the potential use of natural air reduces operating costs and improves energy efficiency.

IEQ upgrade


Salt solution is a natural preservative—it can purify air by removing most microbes, bacteria, viruses, and filter out most respirable particulate matter. In air, most bacteria are attached to fine carriers (vectors) and dust particles. When in contact with the solution, more than 92% of these can be removed and filtered out, effectively purifying the air. According to experimental results, the majority of microorganisms cannot grow above a certain concentration of salt in solution. DOAS technology system allows independent adjustment of temperature and humidity. Our system prevents air duct and heat exchanger surfaces from propagating mildew and microorganisms, thereby improving indoor air quality. Furthermore, it provides high ventilation rates, consumes less power, and also meets ASHRAE 62.1.

LDAC with Heat Pump,Applicable categories: laboratories, hospitals, clean rooms, pharmaceutical biotechnology, libraries, museums, shopping malls and other large spaces and places with environmental control requirements

Flexible Applications

  • • Processing functions include dehumidification, cooling, humidification, heating, and other treatments of air—meets your environmental control and air-conditioning requirements.
    • Capable of precise dehumidification to meet special process requirements—suitable for places requiring constant temperature and humidity or low humidity (moisture content not less than 1.5 g/ kg of dry air, relative humidity not less than 20%) such as industrial buildings, factory processes, museums, storage spaces, clean rooms, biotechnological and medical environments, etc.
