How is the quality of Hisense central air conditioning? What about the price

Hisense central air conditioning is of good quality and moderate price. Hisense air conditioner has extremely low noise, greatly widened frequency range, improved motion accuracy, greatly reduced leakage loss and over-compression loss, and improved energy efficiency by more than 5%.

Compressor is one of the factors to evaluate the quality of air conditioning. The air-conditioning products produced by Hisense are internationally renowned compressors, and the better the quality, the more stable it will be.

High-quality compressor combined with multi-directional sensitive temperature sensing system in air conditioner can keenly control the cooling and heating state of air conditioner, effectively realize the optimization of compressor operation state, easily obtain efficient temperature control effect, and reduce the energy consumption of air conditioner operation.

Principle of air conditioning refrigeration

Liquid vaporization refrigeration uses the heat absorption of liquid vaporization and the heat release of condensation to realize refrigeration. Liquid evaporates to form steam. When the liquid (refrigerant) is in a closed container, there is no other gas in the container except the liquid and the vapor generated by the liquid itself. Liquid and steam will reach equilibrium under a certain pressure, and the gas at this time is called saturated steam.

Pressure is called saturation pressure and temperature is called saturation temperature. When the liquid is in equilibrium, it will no longer evaporate. At this time, if a part of steam is pumped out of the container, the liquid will inevitably continue to vaporize to generate a part of steam to maintain this balance. When a liquid vaporizes, it absorbs heat, which is called latent heat of vaporization.

The latent heat of vaporization comes from the cooled object, which makes the cooled object cool. In order to make this process continue, it is necessary to continuously extract steam from the container and condense it into liquid before returning to the container.

If the vapor extracted from the container is directly condensed into liquid, the temperature of the required cooling medium is lower than the evaporation temperature of the liquid. We hope that the condensation of steam is carried out at room temperature, so it is necessary to increase the pressure of steam to the saturation pressure at room temperature.
