The invention discloses a condensed heat recycle device of central air conditioner, which can solve the defects of present technique as lower efficiency, high energy consumption and worse flexibility. Wherein, the invention is connected to the refrigerating system; a heat recycler is arranged on the tube between the compressor and the condenser of refrigerating system; the input of heat recycler via condensed heat recycle pump is connected to the external water resource; the output of heat recycler is connected to the hot water supplier; the output of heat recycler is connected to a temperature sensor; said temperature sensor and the condensed heat recycle pump are both connected to the intelligent control box. The invention can improve the refrigerating efficiency, reduce the operation cost, save energy and reduce the environment pollution.
Description
technical field [0001] The invention relates to the technical field of energy saving, in particular to a central air-conditioning condensation heat recovery device. Background technique [0002] For a long time, people have relied on central air-conditioning and electric refrigeration units for refrigeration to provide people with a comfortable living environment in hot summer. However, there has not been much attention to the large amount of heat generated by the central air-conditioning electric refrigeration unit in the working process, so that a large amount of heat is not effectively utilized after being discharged into the atmosphere, and is wasted in vain. On the other hand, people are exploring various solutions for how to quickly and effectively reduce the temperature of the central air-conditioning cooling water and save the power consumption of the refrigeration unit. [0003] In order to solve the above problems, someone applied for a patent called a combined ce...
