Problems solved by technology

There are several problems in this control scheme: (1) The heating operation time is not fixed, often the outdoor condenser is frosted and oversaturated, the heating is still running, the efficiency of the outdoor heat exchanger is poor, and the heating capacity is low; (2) The defrosting time If it is too long, the frost on the fins of the outdoor heat exchanger has melted, and the machine is still running in the defrosting mode; (3) The compressor stops for two minutes in total, which accounts for a large proportion in the unsteady heating cycle

Embodiment Construction

[0027] see Figure 2-Figure 4 , the control method for increasing the low-temperature heating heat of an inverter air conditioner of the present invention includes the following steps after the outdoor electronic control chip of the air conditioner receives the start of the indoor low-temperature heating mode: Step 1: The outdoor electronic control chip responds to the outdoor environment temperature and relative humidity of the environment, so that the air conditioner enters the corresponding low-temperature heating operation state; and step 2: after the air conditioner enters the low-temperature heating operation state, the compressor operates at the specified heating frequency for the corresponding heating time Afterwards, the air conditioner enters the defrosting operation, and the outdoor heat exchanger of the air conditioner is defrosted by reversing the four-way valve in the air conditioner. During the whole process, on the premise of keeping the compressor of the air c...

Abstract

The invention provides a control method for increasing low-temperature heating heat of a varied-frequency air conditioner. After an outdoor electronic control chip of the air conditioner receives an instruction to start an indoor low-temperature heating mode, the method comprises the following steps: step 1: the outdoor electronic control chip responses outdoor ambient temperature and environmentrelative humidity so that the air conditioner can enters into a corresponding low-temperature heating running state; and step 2: after the air conditioner enters into a low-temperature heating running state, a compressor runs for a corresponding heating time according to a designated heating frequency, then the air conditioner enters into a defrosting operation and an outdoor heat exchanger of the air conditioner can be defrosted through reversing a four-way valve in the air conditioner, wherein before the defrosting operation in the step 2 and in the entire process of defrosting operation, the operation frequency and time of the compressor can be changed on condition that the compressor of the air conditioner keeps running all the time. The method provided by the invention can response the changes of ambient temperature and relative humidity and can effectively improve low-temperature heating heat of the varied-frequency air conditioner.

Description

technical field [0001] The invention relates to a control method for increasing the low-temperature heating capacity of an inverter air conditioner. Background technique [0002] At present, the low-temperature heating operates according to the set frequency. The running heating time is determined by the accumulated running time of the compressor and whether the chip calculation system enters the defrosting mode. The compressor stops running for 1 minute before defrosting and after defrosting. The defrosting time is determined by whether the chip calculation system exits the defrosting mode. There are several problems in this control scheme: (1) The heating operation time is not fixed, often the outdoor condenser is frosted and oversaturated, the heating is still running, the efficiency of the outdoor heat exchanger is poor, and the heating capacity is low; (2) The defrosting time If it is too long, the frost on the fins of the outdoor heat exchanger has melted, and the mac...
