Abstract
The utility model discloses an air conditioner outdoor unit and an air conditioner. The air conditioner outdoor unit comprises a motor bracket and a motor fixed on the motor bracket, wherein protective hoods for separating the motor from the outer side are arranged on a motor outer cover, and are fixed on the motor bracket. According to the utility model, a front protective hood and a rear protective hold are utilized to seal the motor in an isolated space, once the motor generates sparks while a refrigerant leaks, the refrigerant can be effectively separated from the sparks generated by the motor to avoid the burning and even explosion of the air conditioner, and the safety performance of the air conditioner is improved; and meanwhile, the structures of the air conditioner outdoor unit and the air conditioner are simple and reasonable.
Description
Technical field
The utility model relates to air-conditioning technical field, relates in particular to a kind of air-conditioner outdoor unit and air-conditioner that can use as flammable refrigerants such as R290, R32.
Background technology
Existing air conditioner refrigerant adopts the R22(F-22 more) and R410A(difluoromethane or pentafluoroethane), but, from the ODP(octyl-decyl phthalate) and GWP(Global Warming Potential, chamber effect potential value) index is weighed, and above-mentioned two kinds of cold-producing mediums have greater environmental impacts.Along with energy-conservation and environmental protection requirement is more and more higher, the cold-producing medium of how selecting to have fewer environmental impacts becomes the key of field of air conditioning research.Under above-mentioned background, produced the combustible refrigerant of low GWP value, as R290(propane), the R32(difluoromethane) etc.But, because such cold-producing medium has combustibility, therefore be necessary at air-conditioner corresponding safety measure to be set.
In existing air-conditioner outdoor unit, because motor exposes in the residing space of outdoor heat exchanger, when using the air-conditioner outdoor unit generation leakage of refrigerant of combustible refrigerant, if motor produces electric spark, just might become ignition source, cause potential safety hazard.
