Compressor drive control method for cooling and heating dual-purpose air conditioner
First Claim
Patent Images
1. A control drive method for an air conditioner comprising the steps of:
- comparing a compressor temperature with a lubricating oil freeze temperature if the air conditioner is not in an operation-on status and performing a stand-by control operation for discriminating whether an operation-on status exists, and when the compressor temperature is below the lubricating oil freeze temperature, for raising the compressor temperature above the lubricating oil freeze temperature; and
when the air conditioner is in an operation-on status and an air conditioning operation is discriminated responsive to an operator'"'"'s instructions in an operation-on status, comparing the compressor temperature with the lubricating oil freeze temperature and performing the air conditioning operation when the compressor temperature is above the lubricating oil freeze temperature and performing an operation-on stand-by control operation for raising the compressor temperature for a certain pre-set time duration if the compressor temperature is below the lubricating oil freeze temperature.

Abstract
The present invention relates to the cooling and heating dual-purpose air conditioner, and more particularly to the heat pump type cooling and heating dual-purpose air conditioner wherein the stand-by control is performed in order to prevent the viscosity increases caused by the lubricating oil freeze in the compressor occurring at the initial cooling operation stage and therefore the smooth drive of a compressor in an air conditioner is performed by the preventing of the lubricating oil freeze.
