CASE STUDIES: HTF COMPACT APPLIED

NEW YORK BOTANICAL GARDEN BUILDING, NEW YORK, USA

Case studies - HTF Compact Applied in the New York Botanical Garden Facility in New York City. This energy savings study demonstrates performance of a cooling system during a period of a full year following the installation of HTF Compact. Aim of the study is to demonstrate performance of HTF Compact as heat transfer fluid. In addition, it has been requested to assess performance throughout different seasons considering the consumption pattern varies with the outside temperature and the ambient conditions.

CASE STUDIES - DESCRIPTION

NEW YORK BOTANICAL GARDEN BUILDING, NEW YORK, USA

Case was performed at New York Botanical Garden within a cooling system of 3.25 m3, having ethylene glycol (45%) and water as coolant, where DCAS (Department of Citywide Administrative Services) is in charge of the operations and facility management services of the building. DCAS is in charge of the facility management of the premises and was in charge of the introduction and monitoring of the performance period of HTF Compact during the recorded time.

Prior to the introduction of HTF Compact, a full 12 month baseline was recorded in order to make sure a full year operation can be measured. The main objective is to reduce any potential effect related to seasonally dependent variables. This allows to gain confidence in assessing the performance of the nanofluid and demonstrate that product is designed to produce efficiencies and savings at all times without a dependence on seasonal behavior.

HTF Compact was introduced in September 2017 and data recorded for 12 months continuously so that a one to one comparison could be performed against the baseline.

The Measurement & Verification Methodology was utilized following the strict guidelines of the EVO (Efficiency Valuation Organization and its IPMVP (International Performance Measurement and Verification Protocol) Core Concepts from 2014 and a whole facility concept was selected (Option C).

Additionally, the City University of New York was engaged as the independent entity responsible for final endorsement of the savings.

Results were validated independently at CUNY and HTF Compact was endorsed as a nanofluid to be further utilized at other installations in the network. After two years of operation, HTF Compact remains in place with no decrease in its performance allowing continuous savings generation and contributing to sustainability of the installation.

DEMONSTRATION TEST AT TECHNI PROCESS FACILITY, FRANCE

INTRODUCTION

Pilot Test was carried out in 2019, at Châteauneuf-le-Rouge, France. A temporary testing facility has been mounted for this purpose in order to replicate a commonly used heat transfer system. Tap water was utilized as the hot stream to be cooled down. A chiller was installed as source of cooling with the aim of cooling down the tap water stream Aim of the pilot test was to verify enhanced heat transfer created by the introduction of HTF Compact into a base coolant solution composed of 30% ethylene glycol (remaining water) in a process application for cooling. The main assessment to be performed is around the chiller performance.

FACILITY CONFIGURATION

RESULTS

Energy efficiency by the introduction of HTF Compact (5% v/v) is demonstrated as minimum 15% (±3%) vs baseline conditions (glycol + water).

Performance is measured in relation to the chiller operations time assuming a similar operation throughout the various cases. That means % of time during chiller operating cycle in order to achieve the same cooling setpoint of 5°C.

When HTF Compact is introduced and circulating, setpoint can be reached with chiller operating at 86% of the time.

INHOUSE TESTING FACILITY AT BRINDISI, ITALY

CASE STUDIES

Case Studies - HTF Compact, at our headquearters in Brindisi, Italy, TCT Nanotech is able to perform testing of different configurations of nanofluids in order to match customers requirements. We are able to test dynamically different heating and coolant fluid compositions and concentration of HTF Compact and other proprietary nanofluids. The facilities comprise testing environments to simulate chiller and heat pump systems as well as thermal property evaluation of different heat transfer fluids.

We offer solution development services allowing the customer to gain confidence in the solution by showing online results of how HTF Compact impacts heat transfer systems and results in electrical consumption savings.
