Performance analysis of a novel heat pump type air conditioner coupled with a liquid dehumidification/humidification cycle

An Intelligent System to Automate Humidity Monitoring and Humidifier Control using Internet-of-Things (IoT) and Artificial Intelligence

“…AC also plays the role of a dehumidifier since it removes water vapor in the air. [5] When air hits the cold evaporator coil inside the air handler, the AC makes the humidity condense on the oil and drain into the pipe that then exits outdoors. This also applies to the AC's heating system as well.…”

Experimental investigation of an Air Source Heat Pump

“…Describing the realistic Carnot cycle is a matter of knowing heat pump working principle, the refrigerant cycle used for specific application [6], conduct to confident analyse data after simulation with good result after implementation. Taking into consideration the compressor isentropic efficiency and electrical power consumption, we can write Equation (1) and for Coefficient of Performance it is commonly used Equation (2) [7]:…”

“…For known data, such as temperatures of refrigerant state, condensing/evaporating temperatures, we can simulate the behaviour of system, we can extract whatever parameters are in interest but also to define some parameters which cannot be measured. By equalization, Equation (4) and Equation ( 5) become together the expression of thermal balance between evaporator and condenser environment, given by Equation (6), were parameters cth and ctl are described by Equation (7) and Equation (8), noted RCTCs (refrigerant cycle temperatures coefficients), we are able to estimate electrical power, on compressor inlet. This is possible taking into consideration compressor type efficiency, known RCTCs, but, more important condenser power.…”

Investigation of the Performance of Heat Pump Waste Heat Regeneration Runner Dehumidification of Air Conditioning Systems

“…However, there are still some problems in the application of air-source heat pumps, including low COP of cooling and heating conditions, large air supply temperature difference, and obvious blowing sensation, which affect the thermal comfort of the human body, and the inability to meet indoor requirements [2,[6][7][8][9][10], and the independent control requirements for temperature and humidity [11][12][13][14][15][16]. The study by [17] proposed an air conditioning system coupled with a dehumidification runner and a medium and high-temperature heat pump. The runner processes return fresh air and the heat pump is utilized to completely meet the recovery temperature and load requirements.…”
