Ultra-Low Temperature Air Energy Industrial Modular Air Cooled Water Chiller and Heat Pump Air Conditioner

The modular air cooled chiller and heat pump is designed for cooling and heating operations in large commercial and industrial buildings. The chiller and heat pumps will often be installed in malls, hotels, hospitals,and office buildings. The machine set can be installed on the roofs balconies,courtyards,and other suitable outdoor positions. The equipment does not need to be installed in a specially built water chiller machine room.

1. Easy to install and save space. 
2. 100% heat recovery is for optional.
3. Modular design. Each cooling system operates independently of the others.
4. Equipment can be fully assembled on site. Standard modules are light weight and take up little space.
5. In accordance with the requirements and needs for cooling / heating the client, we create various combinations of modules.
6. In the process of starting the operation of the equipment, the alternate start of the compressors is carried out using a computer, which reduces the current impact on the power supply network.

The Difference Between Ultra-low Temperature Air Energy Heat Pump and Ordinary Air Energy Heat Pump

1. The operating conditions of the two are different
   We all know that the working principle of the air energy heat pump is to convert the heat in the air into the available high heat energy through the compressor, and then exchange it with the water system to provide hot water, heating, cooling, drying and other purposes. The temperature environment in which the ordinary air source heat pump operates is preferably within minus 10 ºC. If it operates at minus 10 to 25 ºC, it may appear:
2. Compressor is prone to failureThe temperature of the exhaust gas rises rapidly, and the overheating of the working medium is too high. In the case of overheating of the working medium, the thermal conductivity of the working medium in the condenser decreases sharply, and at the same time, the temperature of the lubricating oil increases and the viscosity decreases, which affects the normal lubrication of the compressor.
3. The unit cannot defrostIn frequent rain and snow weather and low temperature, the defrosting ability of the unit is easily weakened. Because the air intake of the unit is too small, the density of the air that can be inhaled is reduced. With the accumulation of time, the thickness of the frost layer is getting higher and higher. Therefore, the unit will reduce the circulation of the refrigerant due to the decrease in the air conversion capacity, and the overall heating capacity will decrease.

1. Ultra-low Temperature air Energy Operation Technology
   Air energy heat pump manufacturers have their own ultra-low temperature technology. Since the air energy heat pump host is generally installed outdoors, the phenomenon of frost will frequently occur in rainy and snowy weather. The ultra-low temperature air energy heat pump host can intelligently judge the defrosting needs, and intelligently judge whether to defrost according to the operating conditions of the unit (running time, exhaust temperature, etc.), combined with the ambient temperature and frost thickness. Defrost with frost and no defrost without frost, greatly extending the defrosting cycle, shortening the defrosting time by 20%, and ensuring the efficient operation of the unit
2. Jet Enthalpy Technology Because the heating efficiency of the air-energy heat pump in extremely cold weather will be greatly attenuated, resulting in an unsatisfactory heating effect.The ultra-low temperature air energy heat pump uses the jet enthalpy increase technology to create a second suction port on the scroll, and through the second suction circuit, the refrigerant flow is increased, and the circulation volume of the unit is increased during cooling.Compared with the general unit, the cooling capacity is increased by 10%, which greatly improves the refrigerant circulation system, makes full use of the refrigerant flow and utilization rate in the compressor, and improves the stability of the system operation and the heating efficiency.
3. Shell and Tube Heat Exchanger,Ordinary air can use plate heat exchanger, which is easy to scale and block the flow passage. Lowtemperature air can use copper tube with internal thread and external fins. Water inside the tube and fluorine outside the tube. The heat exchange area is large and the heat exchange efficiency is high.
