A historic London delicatessen is using Toshiba heat pump-based air conditioning and a TCUK air curtain to reduce energy costs.
Panzer’s in St John’s Wood first opened its doors in 1944 and became a much-loved food destination as London’s original Jewish deli, offering culinary delights from around the world.
The shop recently underwent a major refurbishment and, due to the high level of customers, was experiencing significant unexpected energy running costs due to the frequency of the automatic door opening. This resulted in discomfort for staff and customers and high energy bills. Air conditioning specialist Pure Cold Solutions was hired to investigate and find a solution.
Pure Cold Solutions Managing Director Jason Bennett said: “Our client had looked at a number of potential options to improve energy efficiency. We did some calculations on the energy savings that could be made by installing a high-efficiency heat pump-based over-door air curtain, and it was compelling. On the strength of the savings, our customer opted for the TCUK solution.”
Installed above the main front door, the air curtain provides a continuous high-velocity down-draft of air, creating an invisible barrier that prevents incursion of ambient air from outside when the door is open, retaining energy and maintaining comfortable temperatures in the shop at all times.
The unit is connected to a Toshiba Digital Inverter outdoor condensing unit. For enhanced performance, the air curtain uses EC motors with full 0-10V speed control, enabling air speed to be precisely matched to the unit’s mounting height. Precise control of motor speed also allows low noise operation.
“It has proved to be a highly effective solution,” added Jason Bennett. “The shop’s air conditioning is no longer trying to heat or cool the entire surrounding neighbourhood of St John’s Wood, and the indoor climate of the store is kept stable and comfortable irrespective of the number of door openings, even at the busiest periods.”
Panzer’s is famous for its Scottish smoked salmon, which is hand sliced to customers’ requirements, and its huge variety of freshly baked bagels. In-house chefs in kitchens below the shop prepare a hot lunch daily, as well as deli staples such as hot salt beef, fresh dips, chicken schnitzel and chopped liver.
