Energy-saving type hot water and cold air supply system

Abstract

The invention discloses an energy-saving type hot water and cold air supply system. The system is provided with a cold water inlet and a cold water outlet in a first water storage space; a warm water inlet and a warm water outlet in a second water storage space; a hot water inlet and a hot water outlet in a third water storage space; a heat exchanger which is provided with a first pipe communicated to the cold water outlet, a second pipe communicated to the warm water inlet, and a coil pipe provided with a refrigerant inlet and a refrigerant outlet; a solar heat collection plate which is provided with a third pipe communicated to the warm water outlet, a fourth pipe communicated to the hot water inlet; a cold air machine which is provided with a fifth pipe communicated to the refrigerant outlet, and a sixth pipe communicated to the refrigerant inlet. When cold air is used for generating warm water, the system can improve the temperature between solar hot water and supplied hot water, so as to reduce the number of used auxiliary electric heaters, and achieve the energy-saving effect.

Description

technical field [0001] The invention relates to an energy-saving hot water and cold air supply system. Background technique [0002] At present, most households install air conditioners and electric water heaters in order to live comfortably. Both air conditioners and electric water heaters consume a lot of electricity, and the heat energy discharged to the atmosphere by the condenser of the air conditioner is also a precious energy source, which is a pity to discard. Due to the lack of energy, solar energy is one of the inexhaustible and inexhaustible alternative energy sources with the least pollution and damage to the environment. Therefore, in order to meet the requirements of energy saving, carbon reduction and environmental protection in today's families, factories or schools, Many will have solar water heaters installed to save energy. On July 11, 2011, Taiwan announced the new patent case No. M407366 "Water Heater for Reducing Electricity Bills", which discloses: a ...

Problems solved by technology

[0004] However, this prior patent uses the hot air emitted when blowing cold air to heat the water, or uses direct sunlight to heat the water pipes on the iron roof, or uses wind power to generate energy for heating. Among them, the hot air generated by blowing cold air is used to heat the water, the energy utilization effect is not good, and the temperature of the hot water supply is not raised much.
