In fact, even if the crankcase heater is not installed, it is a matter of whether the starting under such conditions adversely affects the reliability of the compressor and whether it can be continuously and reliably operated after starting. In summary, crankcase heaters only improve the performance of the compressor from start-up to stable operation, and crankcase heaters cannot be expected to improve the economics and reliability of the air conditioner. It can be seen that it is technically not a difficult task to require the compressor to start at a lower outdoor ambient temperature, and the biggest problem is how to ensure that the compressor operates within the specified working range and that the motor is fully equipped. Cooling and the good lubrication condition requirements of the moving parts can be met to ensure the reliable operation of the heat pump system. Under this premise, the working quality level of the air conditioner can be said. At present, the heat pump system of some room air conditioner manufacturers in China is more serious in the operation of outdoor temperature in winter, which is much more serious than during the summer cooling operation. Some air conditioners operate at low temperatures in winter, and the continuous damage of the compressors causes the company to pay a high price. Because it is mistakenly considered to be a quality problem of the compressor, it causes conflicts with the compressor manufacturers. Some enterprises do not explain to the user the reasonable operating range of the air conditioner, accommodating the unreasonable requirements of the user, and rashly promise the user that the heat pump can be operated at outdoor temperature. In low temperature areas, the reasonable use of the heat pump system is that in the transitional season, when the outdoor temperature is higher than $#, the heat pump is used for heating operation. Generally speaking, only the heat pump operation can meet the room heating demand. An auxiliary heating system is required to be put into operation. About silicone apple watch bands:
