Efficient environment-friendly energy-saving dual-source double-cooling three-temperature three-effect cold and warm water supply system

Abstract

The invention relates to an efficient environment-friendly energy-saving dual-source double-cooling three-temperature three-effect cold and warm water supply system which mainly comprises a heat pump, a heat exchanger, a gas evaporator and a water evaporator. The heat pump is connected with the heat exchanger through a pipe, and a three-way valve and a four-way valve are mounted on the pipe for connecting the heat pump and the heat exchanger. The heat exchanger is connected with the gas evaporator through a pipe, and a filter, an electronic expansion valve and a reversing valve are mounted on the pipe for connecting the heat exchanger and the gas evaporator. The gas evaporator is connected with the heat pump through a pipe, and a gas-liquid separator is mounted on the pipe for connecting the gas evaporator and the heat pump. One end of the gas evaporator is connected to the pipe between the water evaporator and the four-way valve, and the other end of the gas evaporator is connected with the reversing valve. A hot water heat exchanger is connected with the four-way valve through a pipe, and a one-way valve is mounted on the pipe for connecting the hot water heat exchanger and the four-way valve. The efficient environment-friendly energy-saving dual-source double-cooling three-temperature three-effect cold and warm water supply system has the advantages that coolant in the system is driven by the heat pump to absorb heat in air and water to power a cold and hot water supply unit, and environment protection and energy saving are evidently effective.

Description

technical field [0001] The invention relates to a high-efficiency, environment-friendly, energy-saving, dual-source, double-cooling, three-temperature, and three-effect heating and cooling water heater system, which is mainly used in the field of ordinary household and commercial heat pump water heaters. Background technique [0002] The air conditioners currently in use, whether they are commercial air conditioners or household air conditioners, have a single function to adjust the air temperature. When the air conditioner is cooling, the hot airflow discharged from the condenser will cause thermal pollution to the environment and cause the greenhouse effect. The utilization rate of the system is only 50%, the energy utilization rate is only 45%, and the energy efficiency ratio of the air conditioner is only between 2.6-3.0. Energy waste is serious. The water heaters currently in use, no matter whether they are electric or fuel water heaters, have a single function of hot ...

Serious waste of energy

The water heaters currently in use, whether they are electric or fuel water heaters, have a single function of hot water supply. The energy efficiency ratio of electric water heaters is 0.95, and the energy efficiency ratio of fuel water heaters is between 0.5-0.7. The thermal efficiency is very low and the pollution is serious.
