Proton, the company which accounts for the largest share of the domestic market in dehumidifiers, has announced that, because it exports 56,000 units a year to the U.S. and wishes to avoid the CFC surtax, three years ago it cooperated with Matsushita of Japan to develop an HCFC-22 refrigerant compressor for use exclusively in Proton dehumidifiers. Most of the Proton dehumidifiers exported are of this new variety.
國內除濕機市場佔有率最高的普騰電子錶示，由於普騰一年約有五、六千台的除濕機銷往美國，為了避免課 CFCs 附加稅，公司三年前就和日本松下電機合作開發普騰除濕機專用的 HCFC-22 冷媒壓縮機，目前普騰的外銷機種大部分已改成新機種。
