Defrosting method of strong heat air conditioner

Abstract

The heat-flash air conditioning and its method of defrosting and it is in characterized in that: in the indoor machine sets up a big power secondary electric hot device and the big power secondary electric hot device's electric heat power is 0.9 to 1.4 times to the system's standard cooling quantity. When it is defrosting keep the indoor cross flow flan running in low speed and at the same time open the big power secondary electric hot device with the circulate system in the work condition of cooling. The invention can make the heating quantity of system reached two times or more to the cooling quantity so it is satisfied the small cooling quantity and big heating quantity of the setting requirement of system especially it is suited to the southwest area with the lower temperature and thebigger moisture. During the process of defrosting the fluctuation of environment's temperature is small and the time of defrosting is shorter and the defrosting is more clearly and thoroughly.

Description

technical field [0001] The invention relates to a defrosting control method for a household air conditioner. Background technique [0002] The actual use of household air conditioners has the following two problems: [0003] 1. In different regions, the temperature and humidity vary greatly, and the climate characteristics are also different. For example, the temperature in southwest and other regions is not too high in summer, while the temperature in winter is relatively low and the humidity is high. Local 28m 2 The room needs a 2HP air conditioner in summer, and a small 5HP air conditioner in winter, which is greater than 4HP and close to 5HP. However, the current conventional 2HP fixed-frequency air conditioner has a heat pump heating capacity of only about 1.1 times the cooling capacity. Obviously, if the use of 2HP air conditioners meets the local summer use, it cannot satisfy the winter use; on the contrary, the use of 5HP air conditioners meets the winter use, and...

AI Technical Summary

Problems solved by technology

Since the defrosting effect directly affects the heating effect, it is necessary to prolong the defrosting operation time and increase the frequency of defrosting operation, but this will inevitably affect the heating effect due to insufficient heating time. heat effect

The national standard stipulates: "The defrosting time shall not exceed 20% of the running time", but for areas with high humidity, it will cause a vicious circle due to incomplete defrosting, and the heating effect will be worse every time.

Obviously, there are irreconcilable contradictions between the two. At the same time, due to the discontinuity of heating, the ambient temperature fluctuates in a large range, which brings discomfort to users.
