The objective of this work was to develop and test an electrically-driven, high-temperature heat pump grain dryer of a marketable capacity. An economic evaluation of heat pump grain drying was also conducted. The philosophy and constraints which guided the system design are given. A 60-kW maximum electrical demand is the most significant of these and required that the

12/08/2015 In this paper, a high-temperature heat pump (HTHP) is developed and manufactured to replace the traditional oil-fired boiler heater for crude oil heating. It extracts thermal energy from waste hot water separated from the crude oil to provide high-temperature hot water to heat the crude oil. A prototype of the HTHP system is installed in the Jinzhou oil

High-temperature heat pumps are expected to have the most promising performance in terms of levelized cost of heat in a variety of applications. Extending the range of application to supply temperatures of up to 200 °C would allow high-temperature heat pumps to cover 37 % of the entire process heat demand of the European industry. Objective. The overall objective of the

Liquefied petroleum gas in high-temperature dryers is the predominant method in use today. Escalating costs, unreliable supplies, and the current emphasis on energy conservation have provided the impetus for examining alternative drying methods. One potential alternative is low-temperature heat pump grain drying. The objective of this work is to synthesize a

A high temperature heat pump (HTHP) applies the same technology but at a high temperature. What constitutes ‘high temperature’ is defined loosely across literature and is considered as heat delivery above 100 oC by a heat pump in this paper. The development of heat pumps that can deliver higher temperatures has progressed over the years. Market analysis done by Nellissen
