LS（R）FMModular air-cooled vortex cooling(heat)Water unit

Modular air-cooled (heat pump) chiller unitIt is a central air conditioning unit that uses air as the cold (hot) source and water as the cooling (hot) medium. It is an integrated device that can be used for both hot and cold purposes. The unit eliminates auxiliary components such as water pumps, cooling towers, boilers, and corresponding pipeline systems. The system structure is simple, the installation space is small, the maintenance and management are convenient, and it saves energy. It is widely used in various industrial and civil buildings such as hotels, apartments, restaurants, office buildings, shopping malls, cinemas, factories, hospitals, etc. Especially for situations where water sources are scarce and buildings with high environmental requirements such as boilers or cooling towers cannot be installed, modular air-cooled heat pump chillers are your best choice.

Modular air-cooled chiller is an energy-saving, water-saving, and environmentally friendly air conditioning equipment that can be used for multiple purposes,In addition to meeting the cooling and heating requirements of buildings in summer and winter, it can also supply domestic hot water 24/7, with the characteristic of high equipment (energy) utilization;Modular refers to a unit that can be made into one module, and several units can be operated in parallel without distinction. Air cooling means that the outdoor heat exchanger of the unit is air-cooled and exchanges heat with air. A chiller unit refers to the cold water produced by the evaporator, which directly exchanges heat with the refrigerant. The modular air-cooled chiller unit is the same one that has these performance indicators..

The unit can be set up on open spaces such as roofs and floors, making installation and use extremely convenient. Our company's modular air-cooled heat pump chiller unit is combined with standard unit modules for easy engineering design and selection. We welcome design departments and users to choose.

working principle:

The refrigeration principle of air-cooled heat pump chiller: The high-temperature and high-pressure refrigerant gas discharged from the compressor enters the condenser, and through heat exchange with the cooling medium, it becomes a high-pressure refrigerant liquid. After passing through the filter and throttling by the expansion valve, it becomes a low-temperature and low-pressure refrigerant liquid that enters the evaporator. Through heat exchange with the chilled water, it absorbs the heat of the chilled water and becomes a low-temperature and low-pressure refrigerant gas that is sucked into the compressor. The chilled water provides cooling to the outside due to the decrease in heat release temperature.

Heating principle of air-cooled heat pump chiller: The high-temperature and high-pressure refrigerant gas discharged from the compressor enters the condenser, and through heat exchange with chilled water, becomes high-pressure refrigerant liquid. It passes through a filter and is throttled by an expansion valve to become low-temperature and low-pressure refrigerant liquid, which enters the evaporator and absorbs the heat of the air to become low-temperature and low-pressure refrigerant gas. The chilled water provides heat to the outside due to the increase in heat absorption temperature.
