Xuzhou 圣尔达 Refrigeration Electrical Services Limited air conditioning is not the cause of the three heating, heating and air conditioning division of environmental factors heat pump, heat pump and electric type and electric type three products under equal conditions of heating capacity, the first two power smaller than about half of the third, taking into account the power supply capacity and electricity costs, and now the family generally choose the first two categories and air conditioning (but should pay attention to their conditions of use apply only to the first two under the above -5 ℃ environment, apparently on the northern NA). Heat pump air conditioner, heating when the ambient temperature is too low, the air conditioning energy efficiency is also reduced, not ideal in the colder winter heating effect, which is a normal phenomenon. For non-automatic defrost heat pump air conditioner, which uses the minimum ambient temperature is zero on 5 ℃, below this temperature is not heating or poorly, it is because the external heat exchanger frost blocking the air Xuzhou mobile air conditioning, heat can not be inhaled from the outside sake; for automatic defrost heat pump air conditioner, which uses the minimum ambient temperature is -5 ℃, below this temperature can not be effective heating. Xuzhou Sheng Erda Refrigeration Electrical Services Limited ☆ ventilation (there are two ways): one is through the ventilating device indoor outdoor air intake, and the second is the indoor air out of Xuzhou outdoor air conditioning compressor, outdoor air through slit windows into the room, in order to improve the indoor environment. ☆ inverter air conditioner is a recent development of a highly efficient, energy-efficient new air conditioners. It has changed through the power supply frequency inverter controller input conditioner compressors, compressor speed control continuous change in order to achieve continuous adjustment of the output power conditioner Xuzhou Hisense sales phone that control air conditioner cooling / heating capacity size. Because it is not the same as the fixed-speed air-conditioner compressor intermittent open stop, but continuous operation, so power consumption is greatly reduced, to save power. AC inverter and inverter air conditioner DC inverter two, comparatively speaking, the higher the DC inverter efficiency, more power. ☆ independent dehumidifier affect human comfort is a relative humidity of indoor air, and the relative humidity of the air and the moisture content is not only relevant, but also temperature dependent. When the air conditioner dehumidifier during operation, the fan runs at a lower speed, compressor working intermittently, at the same time effectively remove the moisture content in the air again so does not reduce or slightly lower temperature, which can reduce the relative humidity The purpose, to meet human comfort requirements. Xuzhou old air-conditioning refrigeration lease _ Sheng Erda (certified) _ Air conditioning is provided by Xuzhou Xuzhou 圣尔达 Refrigeration Electrical Services Limited. Xuzhou Sheng Erda Refrigeration Electrical Services Limited (xzktw.com) Xuzhou, Jiangsu, heat, refrigeration and air conditioning equipment leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customers needs. Sheng Erda leader in refrigeration staff warmly welcome all inquiries negotiations to create a better future Sheng Erda refrigeration.
