Abstract
The article presents the possibility of using exhaust air from ventilation system to increase the efficiency (SCOP, COP, SEER and EER) of commonly used air conditioners with the function of a heat pump. These types of devices are very popular both in residential and in public buildings. The topic discussed in the article is very important, because the widespread increase of the energy efficiency of these devices significantly influences national electricity consumption. The possibility of increasing their efficiency by directing the exhaust air from the ventilation system to the heat exchanger of the air conditioner outdoor unit has been analysed. It has been shown that the use of the simple design solution described in the article allows for a significant increase of the efficiency of these devices (seasonal efficiency even up to 35% at 100% share of exhaust air), reducing the energy consumption and increasing their capacity and operation range. By increasing the share of exhaust air it is possible to ensure year-round operation of the device and even 100% coverage of heat demand.
Highlights
Nowadays it is necessary to face the dynamically growing energy demand
Increases the coefficients of performance in the heating mode COP and in the cooling mode EER at particular outdoor air temperatures
Increases the seasonal coefficients of performance the SCOP and SEER devices
Summary
Nowadays it is necessary to face the dynamically growing energy demand This is a very important task for mankind in the face of a dynamic increase of the number of humanity accompanied by the increasing amount of energy consumed by each of us, resulting from the desire to use energy-consuming comforts such as being online, using individual transport, air conditioning in flats and houses. It is very popular to use them in the function of room heating That is why these devices often operate in full-year mode, which increases the impact of their efficiency on the environment. The forecasted popularity of air conditioners in Poland is the growing market of new flats, as the use of these devices is already very popular in office buildings, and in flats and houses [4]. Popularization of the proposed solution may have a significant impact on the reduction of the national energy demand and a significant reduction in the emission of coal combustion products to the atmosphere due to the supply of electricity to these devices in Poland, mainly from coal
