How to solve the exhaust temperature is too high air-source heat pump problems ---2009-10-30
Air-source heat pump can absorb the low-temperature heat in the air came in through the compressor compressed into a high-temperature heat. The air can be a widespread, equitable and freely given to use of low-grade energy, the use of heat pump cycle to improve their energy grade, is a great potential for the development and application of energy-saving, environmental protection and new technologies.
Air-source heat pump water heater with energy-efficient features, its power consumption is an equal-capacity electric water heater 1 / 4, is a gas water heater 1 / 3; and water separation, no waste smoke, exhaust emissions, and therefore no electric shock, poisoning danger , safe and reliable; its wide range of applications not subject to weather constraints and Hou-day continuous heating, easy installation and construction crew.
Current production air-source heat pump water heater, the enterprise can be divided into five categories: 1. The professional production of heat pump hot water machine manufacturers; 2. Air-conditioning manufacturers in transition; 3. Solar power across to the manufacturers; 4. Home appliance manufacturers ; 5. trade categories OEM OEM manufacturers. Product quality varies greatly, so products in the application will certainly there are many problems. The most common problem is that winter and the summer issue of the exhaust temperature is too high, which seriously affected the compressor operating environment, resulting in compressor power consumption increased, decreased machine efficiency; and unreasonable if the system design, then there will be row ultra-high temperature, the compressor does not start properly or even burnt phenomenon.
Study the fundamental reasons are: winter, suction pressure is too low, leading to the compressor pressure ratio increases the exhaust temperature; summer, the ambient temperature rise, in the summer, suction temperature is relatively high heat capacity is relatively high, once the system design unreasonable, it is prone to the phenomenon of excessive exhaust temperature.
At present the general solution for the industry in winter to increase the suction pressure by qi the summer with the spray solution to reduce the suction temperature, while increasing the amount of suction. However, this solution allows the system complexity, control complexity, the cost will increase accordingly, the failure rate will naturally increase. Of course, there are many in the industry companies are eager to find a suitable refrigerant to a fundamental solution to this problem. Excellent performance of the new refrigerant can be a fundamental solution to the air-source heat pump technology bottlenecks in the exhaust temperature is too high.
