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.
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)
What process does the atmosphere release heat? A.precipitation B.evaporation C.condensation D.exploration The answer is C
Sensbile Heat & Latent Heat
lose the heat from the refrigerant
High head pressure is due to the lack of heat removal during the condensing process of the refrigerant cycle. The outdoor condenser is there to transfer the heat out and condense the refirgerant into a liquid. When ever the condenser is dirty or the fan motor is not working right the result is an increase in temp. and since pressure and temp are directly related the refirgerant pressure is increased thus the term high head
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)
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.
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.

In condensation heat is removed In evaporation heat is added
Exothermic is the process that exert heat or giving out energy to surrounding. Example of exothermic process such as condensing of steam or burning of fuel.

Coolant is a fluid at a lower temperature than the process that can be used in heat exchangers. Refrigerants are materials which can go through a refrigerant cycle.
