Fan Coil Units: In-Room Horizontal

December 20, 2021
By: Matthew Crump, PE

Our previous article highlights the variables to consider when choosing a Horizontal Fan Coil design for a project. The highest volume unit type in the industry is the in-room horizontal fan coil unit. The units are ideal for hotel rooms, condominiums, and small offices. They are typically installed above a ceiling and supply directly to the room they serve. The air returns through a grille in the ceiling, either directly into the unit or...

5 Variables to Consider when Choosing a Horizontal Fan Coil

November 4, 2021

Chilled water fan coils are small air handling units that range from 200-4,000 CFM. Several commercially available product types serve multiple applications. In some instances, choosing which product is best for your application is difficult. There are two main configurations: vertical & horizontal. Horizontal units are typically located above a ceiling while vertical units are installed in a closet or exposed in the room. The selection between vertical and horizontal are made during the building design phase, and there will be little debate over where...

Water Source Heat Pump Building Systems: Cooling Tower

November 3, 2020
By: Matthew Crump, PE

In our previous articles we highlighted the benefits, design, energy efficiency, and configurations of water source heat pump technology. Though heat pumps include a refrigeration cycle and air conditioner in one small package, they are only able to do this in cooperation with a few building systems that are critical for removing or delivering heat from/to the heat pump.  To remove heat from the units the building system includes a cooling tower, and to add heat a boiler. The tower and boiler are connected to the heat pumps by a common water loop. Just...

Water Source Heat Pumps: Configurations

October 23, 2020
By: Matthew Crump, PE

Water source heat pump (WSHP) systems have proven in many studies to be a more efficient, less complex, and higher ROI air conditioning selection for a variety of project types.  These systems utilize a building loop of water to reject/draw heat into the individual dwelling unit.  The benefits include no external equipment at each building unit, only one set of (possibly) un-insulated piping for the building loop, and distributed conditioning (one heat pump isn’t affected by the downtime of another).  To meet the needs of different space designs the WSHPs...

Constant Volume Regulators: What are they and how they help

October 6, 2020
By: Kevin Del Castillo

Many obstacles will arise when trying to keep a building 30-50°F warmer or cooler than the outside temperature. The aim of the HVAC system is to keep the buildings’ inhabitants comfortable and healthy while considering system costs. When designing and installing multi-floor supply and exhaust systems, balancing can become an issue.  Fan pressures and thermal stack affects can cause differences in how much supply/exhaust air each floor experiences.  When spaces experience the incorrect amount of supply/exhaust air it can affect the...
