Water cooled and condenserless chiller

There are 2 types of “split” chillers: water cooled and condenserless chillers.

To operate a condenserless chiller, you need a separate condenser. With these chillers, the evaporator, expansion valve, and compressor are located inside the building’s heavily noise-protected engine room, and the condenser is located outside the building, usually on the roof. The condenser fans alone are significantly quieter than the compressor. The two parts are connected by a pair of copper pipes in which the heat transferring refrigerant gas flows. However, in terms of function and assembly, it is identical to a compact outdoor chiller. Its application is limited by the physical distance between the chiller and the condenser (max. About 50 meters).

For water cooled chillers, there is no physical limit on the distance, since heat is transported between the chiller and the outdoor unit (dry cooler or cooling tower) by a mixture of water or water + glycol. However, a pump is required to move it. Due to the number of accessories required, this solution is more expensive than installing a compact outdoor or condenser-less chiller, but with the obstacles listed above (static, noise, distance, image tightness, lack of space, etc.), when installing a water cooled chiller do not arise.

Refigirant gas
ODP GWP
HFC R-410A 0 2088
HFC R-134A 0 1430
HF0 R1234ze 0 6
HFC R-513A 0 631
HFC R-407C 0 1774
R-454B 0 466

The GWP shows the amount of CO2 equivalent to the test substance in the greenhouse effect over 100 years (kgCO2 / kg). The lower the number, the less potent the greenhouse effect.

Ozone depletion is indicated by the ODP value (Ozone Depletion Potential), which can be between 0 and 1.
