Ductless Heat Pump - Refrigerants. R410A

Ductless Heat Pump - Why use HFC?

The HFC, contains no chlorine, is not flammable or toxic. It does not destroy the ozone layer if accidentally released into the atmosphere. The cooling efficiency of HFCs, is equal to or greater than that of HCFC. The use of HFCs are becoming prevalent. It is already widely used in Japan, the United States and, to a lesser extent, in Europe.

Ductless Air Conditioning - What type of refrigerant is R410A?

R410A is a mixture of 50% R32 and R125. R410A components? are harmless to the ozone layer. The ODP (ozone depletion potential) of R410A is 0. The R22 is 0.055. The GWP (direct greenhouse) is 1740, almost the same as the R22 which is 1700.

 

The cooling performance with R410A is higher than that reached with R22. The pressures that work with R410A are between 50% and 60% higher than those of R22

Ductless Heat Pump Reviews - What are the advantages of R410A?

The ODP = 0, does not damage the ozone layer. (ODP R22 = 0.055) with R410A performance is similar to R22 in normal conditions. For high and low temperature capabilities, performance is significantly higher than R410A R22.

 

This high pressure affects the safety of air crews acondicionadas. All components of the units have been developed so that the level of security of these devices equals that we had in the conventional R22.

Ductless Heat Pump Cost - What are the key points in the technical development?

When R410A is used instead of R22, R22 used oil can not be used with R410A due to the impossibility of mixing. So you have to use a new oil for the new refrigerant. The key point is to ensure high reliability using these new products.

 

Another key issue is to optimize the refrigeration circuit and the compressor and the heat exchangers to achieve good performance. We have re-examined all the refrigeration cycle.
