Aquazone 50PSH Water-Cooled Horizontal Water Source Heat Pump

Aquazone 50PSH Water-Cooled Horizontal Water Source Heat Pump

The Aquazone 50PSH Water-Cooled Horizontal Water Source Heat Pump is a high-efficiency heating and cooling system that utilizes the thermal energy of water to provide comfortable indoor temperatures year-round. This model is designed for horizontal installation and can produce up to 50,000 BTU/hr of heating and cooling power.

One of the key benefits of the Aquazone 50PSH is its water-cooled design, which allows for the transfer of heat energy more efficiently than air-cooled systems. This is achieved by using water as a heat exchanger to transfer heat to or from the indoor air rather than relying on air-to-air heat exchangers. The water-cooled design also reduces the amount of noise generated by the system, making it a good option for installations in sensitive areas.

The Aquazone 50PSH uses a scroll compressor, a type of compressor that uses two spiral-shaped elements that rotate around a central shaft to compress the refrigerant. Scroll compressors are known for their high efficiency and reliability, making them a popular choice for heat pumps. 

This particular model also features a variable-speed compressor, which allows the unit to adjust its cooling and heating output based on the needs of the space.

The Aquazone 50PSH is also equipped with a number of safety features to protect the system and the occupants of the building. For example, it includes a high and low pressure switch, which will shut down the system if the refrigerant pressure becomes too high or too low. It also includes a freeze protection feature, which will shut down the system if the temperature of the water in the heat exchanger falls below a certain level.

Another benefit of the Aquazone 50PSH is its ability to provide heating and cooling, making it a versatile option for many applications. It can be used in various settings, including commercial buildings, schools, and hospitals. 

The unit can also be connected to various water sources, including wells, lakes, and rivers, making it a suitable option for both urban and rural installations.

In terms of maintenance, the Aquazone 50PSH requires regular cleaning of the heat exchanger coils and filters, along with the replacement of the compressor oil and the refrigerant. However, it is designed to be easy to service and maintain, with easy access to all internal components. The unit also comes with detailed instructions and a user manual, making it easy for homeowners and technicians to understand and troubleshoot any issues.

Overall, the Aquazone 50PSH Water-Cooled Horizontal Water Source Heat Pump is a high-efficiency, versatile and reliable system that can provide heating and cooling. Its water-cooled design makes it more efficient and quieter than air-cooled systems. In contrast, its variable-speed compressor, safety features, and easy maintenance make it an excellent option for many applications.
