3. Low Installed Cost Advantage
Hang Unit when Tenants Arrive
Small Duct Size
Supply and Return Uninsulated Piping Loop
Unit Above Ceiling Requires No Mechanical Room
Low Installation costs with WSHP are a big advantage than with other types of products. They can be mounted in the ceiling which requires no mechanical room and smaller duct work. These units are can be hung when the tenant arrives or mounted and shut off if that part of the building is not in use.
Ceiling Plenum Return System

4. Redundancy Advantage (1) Chiller = Multiple WSHP Units
Unlike a VVT system with WSHP Redundancy is a big advantage for these products. With VVT one unit with multiple zones is the ideal type of system. With WSHP it is better to have multiple WSHP for the redundancy advantage.

To give you a little detail on what happens inside a WSHP. This shows that in cooling mode we have chilled water coming into the loop with refrigerant that is warm coming into the other side of the loop. The water passes over the refrigerant and cools it. Then air is blown over the cool refrigerant to cool the space. The reversing valve will reverse the flow of the refrigerant when we are in heating mode

7. WSHP Systems Cooling Tower System Water Loop WSHP Units Pumps Boiler
This is a typical loop system for a building as you can see the WSHP units are throughout the building. On the roof there is a cooling tower and in the basement a Boiler. With the UCXP we can control and monitor the loop system, boiler and cooling tower. The UCXP is an optional piece of equipment but since we have waterside linkage the UCXP talks to the WSHPs and controls according to what they need for scheduling, overrides.

This is the WSHP Loop control as you can see the UCXP control the loop water temperature and turns the loop pumps on/off according to what the WSHP needs. We can tie the Loop control into the Tower and Boiler.

9. Integrated System Features and Benefits
WSHP Systems
Integrated System Features and Benefits
Condenser Water Linkage provides optimized Water Loop operation using UCXP Open Loop Controller. Loop pump operation is automatically controlled by WSHP equipment occupancy schedules, unoccupied demand and tenant override conditions. Positive pump status feedback prevents nuisance fault trips.
This Integrated system optimizes your Water loop operation to control your loop pumps according to occupancy schedules, unoccupied demand and tenant override conditions. The UCXP loop controller gives pump status feedbacks to prevent faults.

10. Integrated System Features and Benefits
VVT with WSHP Systems
Integrated System Features and Benefits
Airside Linkage enables complete integration with VVT® Open as system
The WSHP Open responds to individual zone demands rather than average temperature conditions to provide individual temperature control in each zone

Zone Controller and Damper
This new WSHP system has airside linkage which can be fully integrated into a VVT Open System. The WSHP are factory programmed to work with the VVT system. There is no additional controller that you have to buy it will work the the VVT System out of the box.
