First, you have some time to look at questions thirty-one to forty. 00:01:06,080 Now listen carefully and answer questions thirty-one to forty. 00:01:13,860 I'm going to talk about a field trial that was carried out on heat pumps, but first, some background. The UK has adopted a very ambitious target for reducing carbon emissions. Twenty-seven percent of British carbon dioxide emissions come from the energy used in homes. So around a quarter of all reductions must also come from that sector rather than industry. 00:01:40,640 So it's not surprising that the government, private companies, and independent agencies have been looking into green energy alternatives. At present, the most popular green energy from a range which includes wind, biomass heating, and ground heat is solar. This has been the most readily accepted by the public. 00:02:03,700 However, the field trial I've looked at researched heat pump technology. Heat pump technology is relatively new to the UK market, and because there is such limited experience of this technology, people have been reluctant to invest in it. So a field trial was needed to monitor this in a sample of heat pumps in real situations. 00:02:28,640 The heat pumps in this trial are used for the same reason you'd use a boiler, but rather than burning a fuel to produce heat, they move heat from a low-temperature heat source and pump it to a higher temperature, where it can be used to provide central heating or domestic hot water. 00:02:49,160 Most heat pumps take heat from either the ground or the air, but water from ponds or rivers may occasionally be used. 00:02:59,200 The general advice in the UK is that the temperature of the hot water stored in a cylinder should be periodically put up to sixty degrees centigrade to kill off bacteria. It is sometimes necessary to use an electric immersion heater to achieve this temperature, as most heat pump installations will be designed to produce domestic hot water at temperatures between fifty and fifty-five degrees centigrade. 00:03:31,680 For this field trial, eighty-three UK sites were monitored, and they provided a wide spectrum of performance results, even in installations that seemed similar. Some installations performed as well as heat pumps studied in European field trials, but many failed to meet these levels. 00:03:52,760 This field trial monitored two central heat... Many different systems were monitored in the field trial, and it was found that in most cases, designs which were simple were more efficient. So this is something which both pump manufacturers and installers should bear in mind. 00:04:11,240 Many customers mistakenly came to the conclusion that their system wasn't working as well as they'd expected. However, when this was further investigated, it was found that they had not realized how to regulate the controls properly. There had been a failure to explain this in sufficient detail to the householders, 00:04:31,340 and it was often the case that for the installation, all sorts of workmen might be involved. For example, a groundworks contractor, a plumber, a heat pump installer, and an electrician. It was obvious that a supervisor should be appointed to oversee and be responsible for the whole installation. 00:04:52,100 So what are the implications of this technology on a wider ## 题目与答案 ### 31.
