Abstract
The invention discloses a recycling method for an effect-raising anti-freezing solution of an air cooled heat pump. In winter, the air cooled heat pump does not need to run in the defrosting mode, the anti-freezing solution is sprayed to an outdoor heat exchanger of the air cooled heat pump through an anti-freezing solution pump, and frost on the outdoor heat exchanger melts into water and flows into an anti-freezing solution collecting disc; and the anti-freezing solution in the anti-freezing solution collecting disc is diluted, and deicing and defrosting are repeatedly executed in this way. In summer, the air cooled heat pump runs, and an anti-freezing solution diluted solution is sprayed to the outdoor heat exchanger of the air cooled heat pump through the anti-freezing solution pump, so that part of water in the anti-freezing solution diluted solution evaporates, the temperature of the outdoor heat exchanger is reduced, the anti-freezing solution diluted solution becoming thicker flows back to the anti-freezing solution collecting disc, repeated running like this is carried out to reduce the temperature of the outdoor heat exchanger, and meanwhile recycling of the anti-freezing solution is achieved.
