Low ambient temperature air source heat pump (chiller) unit ——
Low ambient temperature air-origin heat pump (cold water) unit shell is made of stainless steel anti-rust and anti-corrosion material, which is durable, double-layer aluminum foil fins for efficient heat dissipation and rapid defrosting. The host adopts air supplementation and enthalpy technology, which can operate normally at -30°C. The heating effect is good in winter. Imported electrical components have a failure rate as low as 0.1%. The unit uses a special compressor for ultra-low temperature heat pumps and has a service life of more than 15 years.
advantage
Cryogenic technology The main engine adopts ultra-low temperature special heat pump compressor, air supplement and enthalpy technology, and can operate normally at -30℃.
Linkage control Linkage control between the host and the terminal reduces host operation and saves energy by more than 30%.
Intelligent remote The host and terminal adopt 485 port design, and remote service is available 24 hours a day.
Anti-rust sheet metal The host is designed with stainless steel sheet metal, with superior anti-corrosion performance, beautiful appearance, and durable.
Modular operation Single or multiple units can be operated modularly, and can be put into work in stages or independently overhauled.
Strength:
The intelligent remote monitoring system developed by the company can monitor the operating status of the equipment at all times. If the operating status is abnormal, it will automatically alarm in the background to troubleshoot the customer in the first time and save time for on-site maintenance.
The anti-leak alarm automatic water replenishment instrument is a national patent product and is used in the water system of the floor heating air conditioner. It can not only solve the automatic water replenishment of the water system, but also determine that the system has reached the alarm function for water leakage. Users can use APP to replenish water in real time to avoid the trouble of manual water replenishment.
The technology has high heat exchange efficiency. It adopts precious metal coating to prevent scaling, with a pressure resistance of up to 30KG. It is professionally used in air energy products and is an alternative product for stainless steel plate and tube heat exchangers.
In the strategic deployment of the “integration of host accessories” for ultra-low temperature heaters, the hydraulic balancer and floor heating air-conditioner integrator have been released to reduce installation thresholds and installation failures, save installation time, and improve the quality of the whole machine and the energy efficiency of the system.
