HFCs (hydrofluorocarbons) are the third
generation of fluorine-based gases.
Zhejiang Zhonglan Refrigerants Co.,Ltd
offers a number of lower GWP HFC solutions, such as R134a, R404a, R406a, R407c,
R410a, R507,R417a,R422d,R125,R32, etc. For new equipment purchases, we also
supply a wide range of HFC alternatives. These include HC(natural
refrigerants), which provide a viable, lower GWP alternative to HFCs.

These products are categorised as having zero ODP (Ozone Depleting Potential)
and medium to high GWP (Global Warming Potential) and so offer a more
environmentally friendly alternative to CFCs and HCFCs.
HFCs are used in a wide range of refrigeration and air conditioning equipment
specifically designed for them, and as "drop
in" retrofit gases for older CFC or HCFC equipment. HFCs are also
used in selective propellant and foam blowing
applications.
A growing focus on the environmental
impact of refrigerants is fuelling demand for refrigeration solutions
that can provide satisfactory cooling performance with a lower impact on global
warming. This is propelling environmentally friendly refrigeration solutions to
the top of the corporate sustainability agenda. In addition, local legislation
is increasingly targeting refrigerant gases with high GWP.
Heat-conducting oil pump maintenance: 1, the heat-conducting oil pump shaft is provided with a stuffing box at the front end, the sealing performance is more reliable, and at the same time, the bearing seat is provided with a mechanical seal device, so a large number of leaks can not occur and a small amount of leaks can leak through Spout discharge to receive. It is normal to have a small amount of leakage early in operation, and the leakage will decrease or stop after the sealing surface has run through a certain period of time. 2, the transmission medium to heat pump oil pump cover and bearing the heat from the pump cover and bearing surface cooling, the temperature of the bearing seat to adapt to the shaft sealing performance temperature. Therefore, the choice of heat transfer oil pump installation location, make the pump cover and bearing seat of the heat for easy proliferation, does not appear any heat storage. 3, the bearing seat is provided with two ball bearings, by the heat pump pump impeller side of a ball bearing with the heat transfer oil lubrication, by the coupling side of a ball bearing is lubricated with high temperature grease: Each ball Bearing 3000 hours after operation, you must remove the clean with diesel, check the contact surface is damaged, if damaged, you must replace the new bearing. When mounted on the impeller-side ball bearing, the dust-proof cover must be mounted on the side facing the impeller and lubricated with heat-conducting oil before starting up. On the coupling side of the ball bearings, the use of complex calcium-based high-temperature grease (ZFG-4), the re-install the bearing, with dust cover side also toward the impeller side installation, install grease (about 1 / 2 ball bearing and housing space). After 48 hours of operation, use a grease gun to inject replenishment grease into the pressure cup on the bearing cap. 4, not allowed to enter the pipe gate valve to regulate the flow, to avoid cavitation. 5, the heat transfer oil pump should not be less than 30% of the continuous operation under the design flow, if you must operate under the conditions, it should be installed in the bypass bypass pipe exports, and to flow above the minimum. 6, often check the loose bolts anchor situation, heat pump oil pump casing temperature and inlet temperature are the same, the export pressure gauge fluctuations and pump vibration. 7, pay attention to the existence of noise conduction heat pump operation, such as the pilot state was found to be timely manner. 8, downtime: cut off the power. The heat transfer oil pump liquid venting, cleaning and should regularly rotate the impeller 180 degrees to prevent shaft deformation until the pump is completely cooled so far.
