Moving the outdoor unit indoors and the indoor unit outdoors is practically impossible. However, by adding a constant temperature aging chamber to the refrigeration cycle and reversing the flow direction of the refrigerant, the issue can be resolved. The device that enables this reversal of refrigerant flow is the electromagnetic four-way valve. With it, the constant temperature aging chamber becomes a reality.

So, how does the constant temperature aging chamber achieve cooling? By utilizing the electromagnetic four-way valve and a cooling/heating mode switch, the challenge of dual functionality is effectively addressed—an ideal solution. Let’s analyze and compare the two distinct cycles of refrigeration and heat pump operation.

Why can the constant temperature aging chamber cool? In fact, while cooling, the condenser emits warm air. Simply put, the aging chamber acts as a heat transporter, absorbing a certain amount of heat from indoors and relocating it outdoors.

Thus, due to the function of the linear constant temperature aging chamber, heat is moved from indoors to outdoors, naturally lowering the room temperature. Specifically, the aging chamber is equipped with a refrigeration system. A refrigerant is sealed within this system, undergoing a series of phase changes during the cycle while exchanging heat with the external environment.

This is a typical single-stage vapor compression cycle. The refrigerant is compressed into high-temperature, high-pressure superheated vapor in the compressor and then enters the air-cooled condenser for cooling.

During cooling, the pressure, temperature, and state of the refrigerant undergo changes. The high-temperature, high-pressure superheated vapor condenses into a high-pressure, medium-temperature liquid (with efficient cooling, it may become a low-temperature liquid).

This condensed refrigerant liquid then enters the capillary tube for throttling and pressure reduction, creating the necessary conditions for evaporation and vaporization in the evaporator. In the evaporator, the liquid refrigerant completely vaporizes into a low-pressure gas while absorbing heat from the surroundings. As a result, the temperature of the evaporator becomes lower than the ambient temperature, effectively functioning as a cooler.

In the evaporator, the refrigerant initially exists as a mixture of gas and liquid before becoming saturated vapor and eventually transforming into low-pressure superheated vapor.
