Hydronic Simulator Tool to Help Educate on the Importance of Valves in Dynamic Systems

    Posted on Tue,Jun 18, 2019 @ 08:30 AM

    Belimo Hydronic Simulator™ is a tool that simulates a hydronic system in a 4-story building with five terminal units on each floor. All terminal units, branches, and the raiser have a manual balancing valve that allows adjusting based on the valve opening. The Simulator identifies and illustrates when the system needs to be balanced and how the adjusting of the valve could impact the entire system. The main purpose of Belimo Hydronic Simulator is to educate on the importance of why pressure dependent valves are not recommended in a dynamic system.

    Pressure Independent Valves a Good Solution for Water Source Heat Pump Application

    Posted on Thu,Oct 18, 2018 @ 09:00 AM

    In a water source heat pump (WSHP) application, a variable or constant speed pump accomplishes water distribution. The primary function of valves in a WSHP application is to allow a predetermined volume of water to enter each unit through either a water-to-refrigerant coil, water-to-air coil, or a water-to-water coil. The valves used are typically on/off control for full design flow when the WSHP starts. In most applications they are not required to control the amount of flow as in a traditional HVAC hydronic system.

    Critical Zone Reset Logic Increases Pumping Efficiency

    Posted on Thu,Oct 04, 2018 @ 08:47 AM

    Hydronic variable flow systems may reset supply water temperature, pump static pressure, or a combination of both to reduce plant energy consumption and to comply with building codes and standards. The information below illustrates how valve position feedback to the Building Automation System (BAS) is used to reset the pump pressure setpoint in accordance with ASHRAE 90.1 and California Title 24.

    District Cooling and the Effects of Low Delta T

    Posted on Mon,Mar 05, 2018 @ 09:36 AM

    District cooling is the centralized production and distribution of cooling energy. Chilled water is delivered from a centralized energy plant through an underground pipeline to commercial, industrial, and residential buildings to air-condition using chilled water.  Excess heat is extracted from the building by the air conditioning systems’ heat exchangers. The water is then returned to the central energy plant.

    District cooling plants operate to meet the cooling energy demand of their customers, which could be dozens of buildings in a college campus or municipality. District cooling systems offer lower up-front construction costs and eliminate the need for chiller plant maintenance at the building level.

    Are Pressure Independent Valves a Good Solution for Water Source Heat Pump Application?

    Posted on Tue,Oct 07, 2014 @ 10:00 AM

    In a Water Source Heat Pump (WSHP) application, water distribution is accomplished either of two ways: variable speed pumping or constant speed pumping. The decision to use one over the other is usually made based on who has the most convincing argument. Because of the simplistic nature of a heat pump, the basic function of valves is to allow a predetermined volume of water to enter each unit through either a water-to-refrigerant coil, water-to-air coil, or a water-to-water coil. These valves are not required to control the amount of flow as in a traditional HVAC hydronic system.  Instead, they are on/off controlled to allow full design flow when the WSHP starts.
