Research and application of heat pump in systems of air conditioner systems and heat providing
This paper aims to characterize the outstanding advantages and applications of heat pumps in the building. Accordingly, the efficiency coefficient of the heat pump is much higher than that of conventional air conditioners. In addition to the ability to cool and heat, the heat pump also has the ability to heat and supply hot water for the living. In addition, this paper also focuses on calculating, analyzing, evaluating and comparing the economic and social effects of a hotel project using a heat pump system to burn and supply water combined with central air conditioning (option 1) compared with only use the heat pump (option 2) and central air conditioning combined with individual hot water tanks (option 3). The results show that option 2 has the highest life expectancy of up to 20 years, and the operation, maintenance and replacement are simpler and easier than options 1 and 3. However, the investment cost of option 1 is second rank (about 2.6 billion dongs), but after ten years the cost of energy is significantly lower than others, at about 278 million (option 2 - 430 million dongs, option 3 - 1,2 billion dongs). Therefore, option 3 not use the heat pump is the energy consumption highest, and should be replaced with the heat pump.
