Abstract
The invention relates to a multilevel energy utilization heat pump system which belongs to the fields of energy saving and environment protection. The heat pump system comprises a compressor, a high-temperature water-cooled condenser, a low-temperature water-cooled condenser, a liquid storage tank, a throttling device, a chilled water evaporator, a pentane working medium and a connecting tube system. The invention can simultaneously supply domestic hot water, hot water for heating and chilled water for air conditioners by utilizing the characteristic that the pressure of the pentane working medium is not too high during the condensation at about 100 DEG C and not too low during the evaporation at 0 DEG C, so that the energy efficiency ratio of the heat pump system exceeds 7.0, and the purposes for energy saving and environment protection are achieved.
Description
Technical field:
The title of patent of the present invention is that multistage energy utilizes heat pump, belongs to energy-conservation and the environmental protection field.It is made up of compressor, high-temperature water cooling condenser, low temperature water cooled condenser, throttling arrangement, chilled water evaporimeter, receiver, pentane working medium, receiver and connecting tube system.When it can utilize pentane working medium to condense about 100 ℃ pressure not really high, 0 ℃ when evaporation the not really low characteristic of pressure and supply with domestic hot-water, heating simultaneously with heat and idle call chilled water, make the Energy Efficiency Ratio of heat pump surpass 7.0, reach the purpose of energy-conserving and environment-protective.
Background technology:
Heat pump has occurred more than 100 year as a kind of energy-saving equipment that low grade heat energy is risen to high-grade heat energy, but its form also has only the heat pump type air conditioning system as the winter heating that freezes summer; The make a living heat-pump hot-water of words hot water of the heat of air conversion is clamored; Utilize the water resource heat pump of surface water, underground water, sanitary sewage, industrial waste heat, these heat pump purposes are single, are difficult to satisfy the requirement of a tractor serves several purposes.There are these heat pump fluids to use R22, R134a, R410a more again, are difficult to satisfy for 100 ℃ of high temperature of giving birth to words hot water and can send 7 ℃ chilled water again for the air-conditioning use, so its Energy Efficiency Ratio has only 4.5-5.0.
Summary of the invention:
In order to remedy above-mentioned deficiency of the prior art, when patent of the present invention will utilize pentane working medium to condense about 100 ℃ pressure not really high, 0 ℃ when evaporation the not really low characteristic of pressure and supply with domestic hot-water, heating simultaneously with heat and idle call chilled water, make the Energy Efficiency Ratio of heat pump surpass 7.0, reach the purpose of energy-conserving and environment-protective.For the inlet UNICOM of the outlet of this compressor and high-temperature water cooling condenser fixed, the outlet of high-temperature water cooling condenser is fixed with the inlet UNICOM of low temperature water cooled condenser again, the inlet UNICOM of the outlet of low temperature water cooled condenser and throttling arrangement is fixed, the outlet of throttling arrangement and chilled water evaporimeter) inlet UNICOM fixed, the inlet UNICOM of the outlet of chilled water evaporimeter and compressor is fixed.Like this when 105 ℃ of gaseous state pentanes sending from the outlet of compressor enter the high-temperature water cooling condenser and condense, just can be heated to 100 ℃ to the domestic hot-water, the working medium that flows out from the high-temperature water cooling condenser enters the low temperature water cooled condenser again and continues to condense, and can be heated to recirculated cooling water about 45 ℃ and use for heating.The working medium that flows out from the low temperature water cooled condenser enters the cold condenser of water at low temperature after by the throttling arrangement step-down evaporates, and chilled water is reduced to about 7 ℃, for the air-conditioning temperature-reducing water, thereby realizes a tractor serves several purposes function.
