In order to improve the heating capacity and comfort of central air-conditioning in winter, York introduced the YES-RM series floor heating central air-conditioning, which adopts the system of "natural fluorine and groundwater", that is, the combination of fluorine system central air-conditioning and circulation system, focusing on rapid heating in winter, which can effectively solve the heating problem in areas with cold winter but no central heating.

It adopts the air source heat pump technology, which can obtain free air energy from outdoor nature and convert it into indoor heat through less electric energy, so the COP value is as high as 4. 19, that is, it can generate 4. 1 9 kwh of heat for every/kloc-0 kwh of electricity consumed, which greatly reduces the electricity cost and can effectively and continuously provide heat even in cold winter.
