A condensing unit accumulator is used to store the heat from an industrial or manufacturing unit such as a boiler or heat exchanger. These units are very similar to condensing air conditioners except they are designed to store large amounts of heat. The heat can be transferred to a building’s cooling system, which will allow for significantly increased cooling efficiency when the unit is switched on. The heating elements are then turned off when the unit is not needed. Many building owners opt to purchase condensing unit accumulators because they typically have longer warranty periods and a lower unit-cost per hour than most other types of heat pumps available.
A condensing unit accumulator is more efficient than the more common electric-powered units that are used in air conditioning. Electric units are more costly to run as well as to maintain. Electric heat pumps are also subject to frequent breakdowns as the power source changes frequently. They do not cool effectively. Meanwhile, the other types of heat pumps are more expensive to operate as well as to maintain.
One disadvantage of a condensing unit accumulator is that they are a bit more difficult to install. A pump mounting kit, for example, must be installed in order to use the unit. Units that use gasoline, propane or natural gas are usually required to be plugged into an on-site fuel source. Installation requires both electric and gas connections and wiring. Installation of electrical equipment is usually straightforward as well as easy, while the installation of gas lines and wires can be tricky. Generally, using a condensing unit accumulator also requires an engineer to oversee installation since many units do not come with a manual.
