Detailed Product Description: | Xuzhou 圣尔达 Refrigeration Electrical Services Limited one, no air conditioning and heating are three major reasons refrigeration cycle system, control system failure 1. insufficient refrigerant. Simple self-test can be performed to identify whether leakage of fluorine. 2. The four-way air valve train. Heat pump air conditioner to switch cooling and heating state by way valve. There should be involved in the heat exchange part of the refrigerant from the compressor outlet pipe directly at the four-way valve returns to the return pipe, leading to contribute to the heat exchange of the refrigerant to reduce the heat exchange efficiency decreases central air conditioning, resulting in insufficient heating capacity. 3-way valve (also known as non-return valve) leak. High cooling system, a low pressure pressure drop Xuzhou modifying telephone central air conditioning, the temperature of the outdoor heat exchanger rises, the heat from the outside to reduce the acquisition, resulting in insufficient heating capacity. Excessive pressure monitoring system is running, you will find the low side pressure rise, high and low pressure drop. 4. defrost controller failure. The air conditioning can not be promptly transferred to defrost running, occurs when heat pump system evaporator frost phenomenon, affecting the air conditioning and heating of the heat exchange efficiency, resulting in insufficient heating capacity, or even stop. Should focus on the observed temperature defrost device is misplaced, contact sticky side or bad, blower wheel slippage or duct obstruction, solenoid or starter relay failure. Xuzhou 圣尔达 Refrigeration Electrical Services Limited (a) performance parameters: ☆ refrigeration air conditioner for cooling operation, the sum of the heat removed from the unit of time in a confined space, room or area, is a measure of the performance of the main indicators of air conditioning one, in units of watts (W) or kilowatts (KW). Total power ☆ cooling power consumption air conditioner for cooling operation, consumed, unit: W. ☆ energy efficiency ratio (EER) at rated conditions and specified conditions, air conditioner for cooling operation, cooling capacity and the effective input power ratio, is one of the key performance indicators to measure the air conditioning, the value is expressed in W / W. ☆ heat capacity heat pump air conditioner heating operation Xuzhou telephone central air conditioning installation, the unit of time into the confined space, the room or the sum of the heat in the region, is one of the key indicators to measure the performance of air conditioning, in units of watts (W) or kilowatts (KW). ☆ coefficient of performance (COP) at rated conditions (high temperature) and specified conditions, air conditioner heat pump heating operation, the heat capacity and the effective input power ratio, its value is expressed in W / W. ☆ circulating air volume air conditioner vent door is completely closed the door and exhaust and cooling operation at rated conditions, confined space within the unit time, room or area into the wind, unit: m3 / h. Xuzhou transformation telephone central air conditioning, refrigeration Sheng Erda (certified), central air conditioning is provided by 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. |
