Technological innovations in heat pump systems 281 Figure 23. Simplified scheme of an absorption heat pump. cold source is well below (even at the same PER) than a conventional electric heat pump. This allows a smaller size of the outside air batteries and lower costs for cold source which are particularly expensive like the ground. Two kinds of machines are on the market: water-lithium bromide and ammonia- water. The latter are more suitable to heat pump mode as evaporation can drop below 0oC so that outside air is a possible cold source. Moreover higher temperatures can be reached arriving even at more than 60oC. In the past very few models were on the market. Long ago an absorption cooling machine was modified in Germany to operate as a water to water heat pump under the Rekord brand, but with bad results. Demonstration devices of higher capacity (250 kW) were also developed as the Dutch Colibrì heat pump that installed an absorption heat pump to heat a big public building at Maastricht in 1993, using as the cold source the near Maas river. The major novelty in this field is the appearance on the market of a series of new absorption heat pumps in the range of 30–40 kW of the air to water type with summer-winter operation and water to water type with possible contemporary heating and cooling. A schematic of the air to water heat pump is represented in Fig. 24. The presenta- tion (much more effective in the animations in the company website [10]) can start from the generator, set on the left that can be identified from the side burner which International Journal of Low Carbon Technologies 2/3 Downloaded from https://academic.oup.com/ijlct/article/2/3/262/758006 by guest on 21 June 2022PDF Image | Technological innovations in heat pump systems
