Is the air conditioner and floor heater noisy?

With the geometric explosive growth of household water machine, the research and development and improvement of household water machine products continue to accelerate. The external machine noise, internal machine noise, pump noise and control transmission and distribution system of household water machine have been greatly improved and transformed. In combination with the needs of users for heating in winter and cooling in summer, the air source heat pump manufacturer changed the household water machine into an air conditioning and floor heating all-in-one machine, which was immediately favored by the majority of owners, and the market heat continued to rise, becoming the best choice for comfortable home at present.

Air-conditioning floor heaters generally use full-DC variable-frequency compressors, fans, ultra-low noise shield pumps, and DC brushless motors. By optimizing the structure of heat exchanger, fan structure, and flow channel design, the wind resistance is reduced, and the unit operation noise is greatly reduced.

Heating noise in winter

Air-conditioned floor heater uses floor heating for heating in winter, and directly heats the air through floor radiation. Compared with the traditional central air conditioner, there is almost no noise in the floor heating room without indoor unit, air outlet, blowing sound, motor running sound, refrigerant throttling sound, frame vibration sound, etc!

Cooling noise in summer

Air conditioner and floor heater use the central air conditioning system for cooling in summer. The specific heat capacity of water is 4.2kJ/(kg · ℃), which is the heat transfer medium with the strongest heat transfer capacity. Only a small water flow can meet the indoor cooling demand, and the flow sound in the pipe can be ignored! However, Freon flows in the central air conditioning pipe of the fluorine system, with high pressure, fast flow rate, gas-liquid two-phase mixture and more obvious refrigerant flow noise.

The air conditioning of the external water system completely relies on temperature difference for heat transfer, while the air conditioning of the fluorine system relies on phase change for heat transfer. The former controls the water flow through the waterproof hammer solenoid valve, and the operation is basically silent. The latter controls the refrigerant flow through the electronic expansion valve, and the refrigerant throttling will have a very obvious "hissing" sound!
