HVAC Systems in Hospitals & Pharmaceuticals Industry

According to CBECS, Hospitals consume approximately 5% of the total energy use which equates to 458 trillion Btus in the USA. Hospitals spend approximately $5 billion on energy per year or 1-3% and most of the energy consumed by healthcare systems arises from the HVAC systems. Chiller plants are the single largest consumer of energy in most healthcare facilities.

This energy use can be exacerbated if the system does not operate at its maximum efficiency. Many healthcare facilities run for 24-hour operations, and therefore chiller plants in pharmaceutical industry operate every day all year round. Therefore, making the chiller plant more efficient is one of the greatest means of reduction of energy use for large healthcare systems.

Chillers generally achieve maximum efficiency when they operate between 65% and 85% of their full load capacity. Chillers operating below 50% of their rated load are usually associated with very large energy consumption and poor energy performance.

By reviewing the normal operating loads and parameters, health care facilities can create an economic dispatch algorithm that can optimize the starting and stopping of chiller plant equipment. The goal of creating the algorithm is to consistently run each chiller machine within its ideal performance range, thus optimizing the overall system efficiency for a given chiller system demand.

Hourly Operational HVAC Load in Pharmaceuticals

Now, we would like to briefly introduce you to what is happening worldwide in regard to the standards of measuring chillers’ Energy Efficiency.  Both within the United States and Australia, and throughout Europe, the HVAC industry has come to a consensus that HVAC equipment typically does not run at full capacity for any significant amount of time, and as such there is a serious deficiency in comparing chillers on the basis of full load efficiency alone. 

In recognition of the actual operating characteristics of air conditioning chillers, the American Refrigeration Institute created IPLV, or Integrated Part Load Values, which provides a weighted average reflecting chiller’s efficiency across a broad range of loads. 

IPLV - Integrated Part Load Values

Seasonal HVAC Load Fluctuation

The seasonal differences of neutral or acceptable temperatures between summer and winter were revealed in the following graph. As for the pre-summer season, the HVAC load can be determined from the load mentioned for March, April, May, and June. According to this graph, the load fluctuation from winter to pre-summer varies from 45% to 100%.

For Bangladesh, the highest environment load for a system occurs from May to August with a rate of 100%. From September the environment load decreases to 20 in December.

Air temperature is found to be one of the most significant drivers for behavioral responses, as Occupants actively control indoor air movement.

SMARDT Oil Free Chiller HVAC System for Hospitals & Pharmaceutical Industry

HVAC improves the pharmaceutical industry with potential safety, product quality, and GMP compliance. The HVAC system within a pharma production house or even a hospital is responsible for the air quality, ventilation units, and exhaust units within a pharmaceutical production house.

Before discussing all the product benefits, let’s just watch a quick video on SQUARE Hospital, Dhaka as a reference for SMARDT Oil Free Chillers for Hospitals. The revolutionary SMARDT chiller compressor with magnetic bearing technology brought out an amazing electricity saving scheme for both of these projects.


SMARDT Oil-Free Chillers Efficiency

Chiller technologies have improved tremendously over the past 20 years, resulting in newer chillers operating at higher efficiency than older model chillers. For example, chillers from leading chiller manufacturers like Daikin, Trane, Carrier, and Johnsons Control have full load efficiencies of between 0.45 kW per ton and 0.5 kW per ton at AHRI conditions.

These magnetic bearing chillers also have integrated part load values (IPLVs) of between 0.29 kW per ton and 0.305 kW per ton. Newer magnetic bearing chillers from SMARDT have integrated part load values as low as 0.29 kW per ton, which can be very attractive for new chiller plants in a pharmaceutical production house.


Efficiency between SMARDT & Oil Chillers

In Bangladesh, SMARDT Oil free chillers was installed and observed in projects like SQUARE Hospitals and Hotel Radisson Blu, Dhaka. The result obtained from the chiller plant room was quite impressive that earned Tritech two separate reorder from the individual client.

Let’s take a look at the yearly bill comparison for SMARDT Magnetic Bearing Oil free chiller with Daikin, Dunham-Bush & Trane Centra-Vac VFD Screw Chiller.

    over a chillers lifetime
  • VSDs reduced power consumption, but increased oil-related issues, particularly at part load.
  • Noise and Vibration are still an issue
  • High Start Up currents remain a problem
  • The size and Weight of Components pose service and installation difficulties.

Problems with typical Oil Lubricated Chillers

Conventional Chillers Require Oil Management

  • Oil Management Adds Complexity
    • Gears – Friction
    • Oil Sump
    • Emergency oil reservoir
    • Oil cooler
    • Oil filter
    • Oil heater
    • Oil Differential pressure switch
  • Additional Complexity Leads to Failures
  • Ongoing Operating Costs related to Oil
    • Oil Sampling, Replacement, Top Ups, Disposal
    • Filters/Dryers/Sensors needing replacement

For a Centrifugal Oil Lubricated Chiller:

  1. 2 pole motor – Need to couple the motor shaft to high speed gear to increase the impeller speed.
  2. Oil Sump is needed. Typically required 15 gallon of compressor oil and yearly oil change is recommended.
  3. Oil cooler is required to remove the heat pick up from the sleeve bearing.
  4. Oil filter to filter the oil before going to the bearing.
  5. Emergency oil reservoir to cater for power loss to the oil pump
  6. Oil heater is required to heat up the oil when chiller is not in operation to prevent oil foaming when compressor start up
  7. Oil Differential pressure switch is the safety device to protect the compressor.

In people’s efforts today to reduce energy usage, often the best solutions are overlooked due to high capital costs.  This could be described as the iceberg syndrome, where the upfront costs are assessed without any regard to the lifelong operating costs associated with their choice.  The price of energy is steadily increasing due to worldwide shortages, and the unseen costs of breakdowns, repairs and major maintenance programs combine to typically outweigh the initial purchase.

Lowest Lifecycle cost for a chiller

The best solution to the high maintenance and life cycle cost is to consider life cycle costs for the equipment when making purchasing decisions.  This slide demonstrates the comparison between using this revolutionary technology compared with using conventional chiller technology over a period of only 2 years. 

Although the more energy-efficient chiller cost more initially, the substantial savings in not only operating costs, but power and noise controls resulted in considerable savings for the owner, both within the 2 years, and then obviously for the life time of the equipment.
