HVAC

HVAC stands for Heating, Ventilation, and Air Conditioning. It is a technical system used to regulate the temperature, humidity, fresh air circulation and air quality of an indoor environment to provide a comfortable and safe indoor environment. HVAC systems typically include heating equipment, ventilation systems, air conditioning equipment, and the control systems associated with them.

Solution

The coaxial evaporator is used to make the water and the refrigerant heat exchange, the refrigerant absorbs the heat load in the water, the water cools down and produces cold water, and the heat is brought to the finned condenser through the action of the compressor, and then lost to the outside air by the cooling fan (wind cooling).

Heat Pump Water Heater
HZSS heating heat pump coaxial heat exchanger is designed for heating-centric hot and cold water units, particularly suitable for the "coal to electricity" market. It offers high heating efficiency while also providing cooling.
Heat Pump Heating Unit
The primary role of the coaxial heat exchanger in the heat pump system is to transfer heat, facilitating energy exchange between the refrigerant and water or air, to achieve heating or cooling.
Commercial Air Conditioner (Heat Pump)
The coaxial heat exchanger in the heat pump system primarily functions to transfer heat, facilitating energy exchange between the refrigerant and water or air, to achieve heating or cooling.
Water (Geothermal) Source Heat Pump
HZSS water (geothermal) source coaxial heat exchanger is specially designed for water and geothermal source heat pumps. It can be used as an evaporator or condenser, offering various shape options, high efficiency, and a compact structure.
Industrial Chiller (Oil Cooler)
The coaxial heat exchanger plays a critical role in industrial chillers (oil coolers). Its unique design makes it an ideal choice for many industrial cooling applications, offering benefits such as high efficiency, space-saving, anti-fouling and durability, easy maintenance, and safety and reliability.
Supercritical CO2 Heat Pump
HZSS supercritical CO2 heat exchanger can be used in CO2 heat pumps or CO2 refrigeration (freezing) units. It is specially designed based on the physical and heat transfer characteristics of transcritical CO2, featuring high pressure resistance and extremely high heat transfer efficiency.
Salt Solution Air Conditioner
In salt solution air conditioning systems, the coaxial heat exchanger, with its compact design, can effectively save space. Due to the direct contact of the two tubes, heat transfer efficiency is high, making it particularly suitable for applications requiring rapid heat exchange.
Swimming Pool Heat Pump
This is a highly efficient heat exchanger made of Ω-shaped high-efficiency inner threaded tube and plastic shell; it ingeniously combines the features of shell-and-tube heat exchangers and plate heat exchangers
Seawater Aquaculture Thermostat
This is a highly efficient heat exchanger made of Ω-shaped high-efficiency inner threaded tube and shell with baffle plates; it ingeniously combines the features of shell-and-tube heat exchangers and plate heat exchangers
Shell And Tube Heat Exchanger
Shen's energy-saving shell and tube heat exchangers have excellent performance, safe use, small size, high cost performance, and are widely used in hot and cold water units, modular machines and so on.

Technical Characteristics

1, good freezing resistance: when the water flows at low speed, it can form a high degree of turbulence in the threaded groove pipe, which is not easy to freeze; The inner tube has spiral groove structure, which has flexibility and better frost resistance.2, self-scaling, not easy to block: fluid spiral flow, with self-scaling ability, stable performance, small attenuation; The water-side runner has a large cross-section size, which is less likely to cause dirty blockage.3, high heat transfer efficiency: spiral groove structure, can play a bilateral role in strengthening heat transfer, the fluid in the tube both along the axial flow, but also along the spiral rotation flow, intensification near the wall of the fluid and the center of the fluid mixing, enhance the turbulence intensity, so that the heat transfer coefficient increases.
