Problems solved by technology

Atmospheric pressure regeneration uses packed tower regeneration. This method is simple, but the regeneration efficiency is low; when vacuum regeneration is used, the regeneration system needs to maintain a high vacuum state during operation, which poses high demands on equipment manufacturing and management. Require
[0005] Membrane methods can also be used to regenerate antifreeze, such as membrane distillation and reverse osmosis. Reverse osmosis does not involve a phase change process, which is more convenient in application. However, reverse osmosis is usually aimed at low-concentration solutions. When the concentration of antifreeze is high, the The operating pressure of reverse osmosis needs to be at least 10Mpa, causing great practical difficulties
In order to reduce the operating pressure of reverse osmosis, the patent

The inventionfurther a method for heat supply or refrigeration on a frost-free heat pump for the reverse-flow reverse-osmosis regeneration through the device. According to the device, the working efficiency and feasibility of an existing frost-free heat pump can be further improved.

Description

technical field [0001] The invention relates to the field of air-conditioning and refrigeration technology, in particular to a countercurrent reverse osmosis regeneration frost-free heat pump system device and a method thereof. Background technique [0002] Traditional air source heat pumps have serious frosting problems in winter, especially in the low-temperature and high-humidity Yangtze River Basin. This phenomenon causes the host to frequently interrupt the normal heating operation and enter the defrosting mode, which not only affects the normal heating but also reduces The energy efficiency of the whole machine is improved. [0003] In order to solve this problem, the industry has proposed two technical routes for the frost-free operation of air source pumps. One is to use a dehumidifier to dehumidify the humid air first, reduce the dew point temperature of the humid air, and prevent the humid air from frosting on the surface of the heat exchanger. , but this method r...
