Exploring the Cold Chain: Reducing Food Waste Globally

While the space temperature in a refrigerated space may be used to control the refrigeration system, there is a lot more going on that we must also take control of. The thermostat initiates a pump down cycle to control/limit refrigerant migration to protect the compressor and enable defrost to occur more rapidly. Control over the temperature, humidity, velocity and direction of air leaving the unit cooler must be maintained to ensure that product is not dried out or frozen even when stored in temperatures above freezing. How product is placed within the cooler or freezer must be controlled so that sufficient airflow through the space and around the product occurs for quick and efficient heat removal. 

In this episode of Taking the Temperature on HVACR, host Jamie Kitchen welcomes special guest Maiken Hansen to explore the world of hydronic balancing. They discuss how unbalanced heating systems in multi-family buildings can lead to cold tenants, noisy radiators, and high energy bills—and how dynamic balancing solutions can improve comfort, reduce complaints, and cut energy costs by up to 25%. Whether you're a facility manager, building owner, or just curious about smarter heating solutions, this episode dives into the challenges and benefits of efficient hydronic balancing.
