Enwave was
looking for a solution to serve as a “thermal well” filled with 8.5 million
litres of Lake Ontario water to heat and cool downtown buildings. To employ
low-carbon heating/cooling system to provide energy to buildings. Enwave
wanted a solution to control the temperature of a large tank that is fed by
the deep lake water cooling (DLWC) to store energy at night to ease stain on the
electricity grid and reduce cost.
Siemens Service experts supplied, installed and commissioned the following equipment:
SIMATIC
PCS 7 V9.0 SP2
SIMATIC
IPC hardware for standalone Operator station
CPU
410E with PA network to connect the instrumentation and actuators
Modbus
RTU interface connected to the chiller units
BAcNET
interface connected with the BT system
S7-1200
PLC to transmit data to the Customer’s iFIX SCADA System
Instrumentation
for Flow, Pressure, Temperature and level connect on the Profibus PA network
using AFD
SITRANS
TO500 - multipoint temperature transmitter for measuring temperatures and
temperature profiles with fiber-optic multipoint measuring lances for the
Thermal energy storage tank
HMI
screen for local operation and monitoring
The
benefit of the project is that the customer wants to achieve a low-carbon
cooling and heating to reduce the dependence on the electricity grid. With the
project completion, the customer will be able to provide a solution with an
option to save energy and reduce carbon emission that helps Toronto.
Enwave is the leading core-competency district energy operator in North America. The Well is a visionary mixed-use development featuring more than 3 million square feet of office and residential space. As part of the development, Enwave invested in an innovative thermal battery that creates and stores energy at night, leveraging off-peak costs. The green and clean technology expands the Deep Lake Water Cooling system to support growth in Toronto’s west end. It also supplies a high-efficiency hot water network to deliver efficient, resilient heating and cooling to The Well and nearby communities.
