specific Embodiment approach 1
[0011] Specific implementation mode one: combine figure 1 Illustrate the present embodiment, the step of the method for preventing frosting is: 1. After adding the low freezing point solution in the sump 2 until the liquid level of the solution is higher than the filter screen 5, open the solution pump 1, the sump 2 The low freezing point solution in the solution is sucked into the solution pump 1 after being filtered by the filter net 5; 2. When the pressure in the solution pump 1 reaches 60kpa-80kpa, the low freezing point solution in the solution pump 1 is transported to the first pump through the solution pump 1. In the solution spraying pipe 3-1 and the second solution spraying pipe 3-2, the low freezing point solution delivered to the first solution spraying pipe 3-1 is sprayed into mist and exchanges heat and moisture with the outdoor air in a large area, Absorb moisture in the air, reduce air humidity by 10% to 50% and dew point temperature by 5°C to 8°C, and the low ...
specific Embodiment approach 2
[0012] Specific implementation mode two: combination figure 1 Illustrate the present embodiment, when the liquid level height of the low freezing point solution in the sump 2 is below the filter screen 5 in the described step one, then open the concentrated solution tank, replenish the low freezing point solution in the sump 2, until The liquid level height of the low freezing point solution in the sump 2 is higher than the position of the filter screen 5 . Other compositions are the same as in Embodiment 1.
specific Embodiment approach 3
[0013] Specific implementation mode three: combination figure 1 To illustrate this embodiment, when the heat pump is running under refrigeration conditions, first, the dilute solution tank is opened, and the dilute solution tank transports the dilute solution to the sump 2 through the pipeline; 2, the low freezing point solution in the sump 2 Flow to the suction end of the solution pump 1 after being filtered by the filter screen 5; 3. After the low freezing point solution increases the pressure through the solution pump 1, the low freezing point solution in the solution pump 1 is divided into two parts and delivered to the first solution spray pipe respectively 3-1 and the second solution spray pipe 3-2, the low freezing point solution delivered to the first solution spray pipe 3-1 is sprayed into mist and contacts with the outdoor air in a large area, and the moisture in the low freezing point solution is evaporate, the concentration of the low freezing point solution incre...
