WhisperKOOL is proud to present our cold weather start kit. This kit was designed exclusively for split systems which will be installed in extremely cold environments. Split systems can be installed in a variety of ways, and the condensing unit may be located in a mechanical room, basement, backyard, or even a rooftop. The condensing units which WhisperKOOL units use were designed to operate between temperatures of 20°F and 110°F. However, there are some areas in the country which may drop below 20°F in winter.
When outside temperatures drop, the pressure in the system drops as well. This presents a challenge, because our systems operate using a pump down cycle and use a low-pressure switch to turn the compressor on and off. However, when the temperature drops below 20°F, the pressure in the system is too low to start the compressor. The cold weather start kit bypasses the low-pressure switch on startup and uses heaters installed on the receiver to raise the pressure and allow the system to start.
The cold weather start kit enables WhisperKOOL to operate in environments as cold as -20°F.
It is important that the cooling system stays operational during cold weather conditions, as heating the house using the central HVAC system will indirectly increase the temperature of the wine cellar. This kit will ensure that the cooling system will continue to operate efficiently in cold weather environments to maintain an optimal wine storage temperature.
