Water Source and Geothermal Heat Pumps
FHP's Geothermal And Water Source Systems
Our heat pump systems are the most energy and cost efficient systems on the market and therefore the greenest technology and the smartest investment for commercial heating and cooling applications.
Geothermal Systems
As the cost of energy increases geothermal installations become the system of choice. The earth has a tremendous capacity for storing thermal energy which can be utilized to heat or cool a building. Although the initial cost of a geothermal application may be higher, if one considers the life cycle savings in energy and the reduced maintenance costs, then geothermal is the smartest decision for your project. Geothermal systems are especially recommended in areas that have significant heating and cooling loads. In areas that are either cooling or heating dominant our hybrid systems could be the perfect solution for your needs. Using a cooling tower in conjunction with a ground loop in areas that have a cooling dominant load reduces the cost of the loop field with only a small impact on the efficiency of the system. Conversely, in areas that are heating dominant, the addition of a boiler to a geothermal loop reduces the loop field cost with a minimal effect on the efficiency of the system.
Water Source Cooling Tower/Boiler Systems
A tower/boiler system offers as excellent alternative to a geothermal system where space is limited or initial costs are a determinant factor. The tower/boiler system consists of a cooling tower that will reject heat absorbed by the loop when the system is predominantly in the cooling mode. The boiler's function is to add heat to the loop when there is a net heating demand. In many instances the heat generated by the units in cooling mode balance the heat loss in the loop for the units in the heating mode. In this situation neither the tower nor boiler will operate as the system is self balancing.
Environmental stewardship is a core philosophy for FHP Manufacturing from design to production to the reduction in our customer's energy bills. At FHP, we are working on a better future every day.
Advantages Of FHP's Technology
Low Installation Costs
FHP water source heat pumps systems provide the most flexible and lowest installation costs of virtually any HVAC system. In a typical installation the water loop remains above the dew point of the ambient air meaning no insulation is required on piping, a major cost of any installation. To accomplish the same degree of flexibility as a heat pump system, a four pipe system is required. This represents another significant cost saving potential since heat pump installations only require a two pipe system for either heating or cooling.
Flexibility And Comfort
FHP units come in a wide variety of models, sizes and configurations. This provides the design engineer true flexibility when designing the system. Should the occupancy of an area change, the unit may be changed out for the appropriate size without major modifications to the layout.
Energy Efficient
FHP units operate individually with high efficiency making the complete system extremely efficient. What makes this system unique is the ability to transfer heat around the building in winter through the common water loop. In today's modern buildings, interior zones generally require cooling even in the winter because of the lighting, occupancy and electronic loading. When cooling these areas heat is transferred to the water loop and utilized by the units on the perimeter that may require heating. This is the only system with this capability and the net result is a truly economical operating system. Individual units serve specific zones so that there is no need to operate large units if there is only a small area calling for heating or cooling.
Redundancy
The building is not dependent on one or two large chillers. With multiple units serving individual zones should one unit fail, only this area is affected. FHP units are designed for convenient, easy and fast service and do not require specialized training to maintain or repair. Downtime should be minimal. Routine maintenance is limited to filter replacement and an annual checkup, making maintenance costs for water source heat pumps one of the lowest of any system.
Space Savings
FHP horizontal units are designed to be as compact as possible. In a commercial application units are typically located above a false ceiling meaning that large equipment rooms that would normally house large chillers or air handlers are not required This frees up space that can now be used for tenant occupancy generating additional revenue throughout the life of the building. Each FHP unit will have its own duct system to serve the specific zone. Large central plant ducting is not required, allowing for the possibility of reduced floor to floor height with a corresponding reduction in the mass and cost of the building.
Operation Modes Of A Heat Pump
Cooling Mode
In the COOLING mode, the refrigerant, a hot gas, is pumped from the compressor to the water-to-refrigerant heat exchanger via the reversing valve. Water, generally with an anti freeze, following through the water-to-refrigerant heat exchanger removes heat and the hot gas condenses into a liquid. This liquid then flows through a metering device to the air-to-refrigerant heat exchanger coil. In evaporating into a gas, the liquid absorbs heat and cools and dehumidifies the air that passes over the coil surface. The cooling cycle is completed when the surface. The cooling cycle is completed when the reversing valve and back to the suction side of the compressor.

During the HEATING mode, the refrigerant, a hot gas, is pumped from the compressor to the air-to-refrigerant heat exchanger coil via the reversing valve. In the air-to-refrigerant heat exchanger coil, the heat is removed by the air that passes over the coil surface, and the hot gas condenses into a liquid. The air is circulated to the space and provides heating for the building. The refrigerant liquid then flows through a metering system to the water-to-refrigerant heat exchanger. While it evaporates into a gas, the liquid absorbs heat and cools the water. The heating cycle is completed when the refrigerant \ufb02ows as a low pressure gas through the reversing valve and back to the suction side of the compressor.
