Low-temperature floor radiation heating and refrigerating system device

Abstract

The invention relates to a low-temperature floor radiation hearing and refrigerating system device, comprising a solar hot water circulating system and a heat pump circulating system, wherein the heat pump circulating system comprises a heat pump unit, an underground water circulating system, a main water supply pipe and a main water return pipe, a water inlet end of the heat pump unit is connected with the underground water circulating system and a water outlet end of the heat pump unit is connected with the main water supply pipe and the main water return pipe, the main water supply pipe isprovided with a temperature adjusting device which is connected with the solar hot water circulating system and the underground water circulating system via pipelines respectively, and the main waterreturn pipe is connected with the underground water circulating system via the pipeline; during refrigeration, hot water is fed to the main water supply pipe via the solar hot water circulating system, the temperature of the circulating water in the main water supply pipe is adjusted by the temperature adjusting device, the circulating water is adjusted to the temperature required by no condensation, the circulating water inside an indoor coil pipe is circulated on condition that the temperature of the circulating water is constantly controlled within the scope of dew point, thus the problem that condensed water can be generated by refrigeration in summer easily can be solved.

Description

technical field [0001] The invention relates to an energy comprehensive utilization device, in particular to a low-temperature floor radiation heating and cooling system device. Background technique [0002] With the development of society, the demand for energy is increasing day by day, and the supply of energy is becoming more and more tense. While energy meets the needs of people's modern life and production, the problem of pollution is also becoming more and more serious. In order to achieve the sustainable development of society, energy conservation and emission reduction, and the development of green, low-carbon, and pollution-free energy have become the priority development direction of all countries. [0003] The total annual solar radiation in my country exceeds 4200MJ / m 2 China occupies 76% of the country's land area, and is one of the countries with the most abundant solar energy resources in the world. The low-temperature energy that can be collected in surface ...
