Hotel Heat Pump Case Study – Randles Hotel Killarney

Complete revamp of existing LPG fired plant room. The new plant room works has been scheduled in two stages. 1st stage – Installation Air source heat pump system and new heat pump optimise calorifiers to heat domestic hot water for the all hotel bedrooms, public areas and kitchen.

Reference description

As DHW heating capacity requirements can be variable (depends on hotel occupancy, shower heads L/s, secondary return heat losses etc. ) The system’s performance has been monitored and logged to estimate possible spare capacity that could be used for hotel space heating outside the DHW peaks. This methods guarantees maximising potential of heat pump units and avoiding unnecessary oversizing and wasting clients capital on unused equipment.

Based on the performance analyses we will be altering the system by adding a number of units to match building heat loss in 2nd stage. This stage will be completed in Summer 2022 and the entire hotel will be supplied heat and DHW solely from the heat pump plant.

The hotel has also installed Photovoltaic solar panels on the roof partially supplying electricity for heat pumps and a few other energy upgrades. Randles Hotel is leading way in carbon savings and sustainability in the hospitality sector.

Simultaneous Heating and Cooling

How to produce up to 9 kWh of usable heat and cold from one supplied kWh

It is a generally known that two biggest energy users in the industrial sector are chilling and heat production.

Chilled water is typically generated by chillers and heat by LPHW or steam boilers.

What if you could get rid of both of these and replace it with one system that is capable to provide both at the same time and use a fraction of energy?

We at MasterTherm have been providing this solution successfully for over 15 years, significantly reducing operational and maintenance costs and achieving significant CO2 savings.

Our purpose built heat recovery heat pumps can recover high or low grade heat, chill and provide up to 82 Degrees heating water all at the same time.

Combination of these can therefore achieve simultaneous COP of up 11.

There are many uses for our heat recovery heat pumps and the list sectors in which our systems can be used is very long. So far we have implemented our technology in following sectors.

• Pharmaceutical

• Food processing

• Wool processing

• Cement and concrete industry

• Food and beverages

• Nuclear – Nuclear testing

• Medical

• Plastic and metal manufacturing and processing

Our Typical Simultaneous Heating and Cooling Plant
Can Operate On The Following Bases.

All units will be controlled by an internal Carel PLCs and MasterLan software.
The CHW circuits is be controlled on constant or variable temperature basis
Rejected heat from the chilling process is allocated to process or LPHW circuit accurately matching heat load.
Control system will decide whether the rejected heat will be reused or reject it
In case the rejected heat could not be used, it will be rejected at the lowest possible temperature to maximise cooling efficiency of the plant.

Advances in technology allow full monitoring of heat pumps online. Through a remote connection, room temperatures, water temperatures and operating parameters are monitored and altered remotely directly from the manufacturer. Data collected from the heat pump and stored, accessible for several years making optimization and analytics easy.
System can by interconnected to the existing BMS via MODbus or BACnet or accessed independently via it’s own interface.
