Adsorption Heat Pump

A sea source adsorption heat pump system driven by steam was put forward in this paper. A mathematic model of the system was established with thermodynamic method by appropriate assumptions.Three parameters were chosen for analysis the system.The results shows that the lower heating temperature,higher sea water circulation temperature and steam pressure will improve the system parameters especially on the conditions of low te and high tc. It may be very useful for design and operation of the absorption heat pump system driven by steam.

Heating Systems

This study compares environmental impact of different heating systems with life cycle analysis, and get out if heat pump system has advantage in replacing boiler heating systems. Systems energy use are compared in one-year operation phase for residential buildings located in Tianjin city, including waste water heat pump system, coal boiler system and gas boiler system. In order to analyzed the environment performance of heat pump system in different conditions. The power structure impact to heat pump systems is analyzed using life cycle analysis method. The results indicate that with COP=4, even if 100% coal power is used, heat pump has advantage in the most impact factors, and if more clean power is used, the environment impact in heat pump system will be reduced obviously. The result also shows that waste water use in heat pump system impact the result little for its small quantity.

High Output

The present research of adsorption heat pump system for heating application mainly focuses on its miniaturization and high output. When the adsorption heat pump is downsized the heat energy is insufficient to meet heating application. In addition, a large amount of low-temperature heat energy in industry has not been utilized but discharged into the atmosphere as waste heat. To improve energy efficiency and reduce carbon dioxide emission, it is important to effectively utilize the low-temperature heat source which is usually discarded as waste heat. In order to solve the problem between the miniaturization and the high output, a miniature all-in-one type adsorption heat pump which can effectively utilize waste heat is designed. In this design, a heat exchanger coated with adsorption material is used as an adsorber or desorber, and another heat exchanger is used as an evaporator or condenser. A seal unit is formed by assembling two heat exchangers into a vacuum tight container and is connected to the surroundings only by hydraulic piping. Moreover, the adsorbent is a functional adsorbent material-zeolite (AQSOA FAM-Z02, Mitsubishi Plastics) which can be regenerated by utilizing the low-temperature heat energy between 75 and 100°C. In this paper the design and experimental performance of this all-in-one type adsorption heat pump are described.
