When the maximum pressure of the refrigerant is achieved in the condensor and the maximum temperature differential is acheived between the condensor coil and the surrounding medium. (air, water, or other)
When the temperature of the air passing over the condenser is very low. Ex: Home A/c with out condenser, More heat can be removed if the out door ambient is 60f compared to 90f. Efficiency also increases with this.
lose the heat from the refrigerant
The compressor compresses the refrigerant gas. This raises the refrigerant's pressure and temperature, so the heat-exchanging coils outside the refrigerator allow the refrigerant to dissipate the heat of pressurization.

All refrigeration cycles operate on the theory of changing states of a refrigerant to remove and reject heat. To remove heat, liquid refrigerant is exposed to the air passing through the evaporator, the removed heat causes the liquid refrigerant to boil, or change state liquid to a vapor, consequently, the heat is rejected by removing heat and condensing the vapor back to a liquid.
When the temperature of the air passing over the condenser is very low. Ex: Home A/c with out condenser, More heat can be removed if the out door ambient is 60f compared to 90f. Efficiency also increases with this.
This is a straight cool 13 SEER condensing unit that uses R410a refrigerant. This is not a heat pump.
Refrigerant is the material that absorbs heat when evaporating and releases heat when condensing. If not for refrigerant in the system, it would not function. Before refrigerant, other more dangerous gases were used to achieve the same goal, such as propane.
First step in refrigeration is evaporation. The next step is compression, which raises the pressure of the refrigerant vapor. Condensing is the third step and is where the heat transfer takes place. Expansion is the fourth step and is where the condenser cools the refrigerant even more, to a level below the condensing temperature.

Yes
A filter drier for a cooling only condensing unit will have an arrow pointing in one direction. This is because the refrigerant that passes through it will always flow in the same direction. A heat pump filter drier must have the ability to allow the refrigerant to flow through it in either direction and so a filter drier that is made for a heat pump will have two arrows pointing in opposite directions.
