CO2 high-temperature heat pump saunas system

Abstract

The invention discloses a CO2 high temperature heat pump sauna system, aiming to provide a CO2 high temperature heat pump sauna system which provides heat for sauna rooms in two modes and has high heat efficiency and low cost. The CO2 high temperature heat pump sauna system consists of a CO2 compressor, a high temperature double-pipe heat exchanger, an indoor wavy finned tube heat exchanger, an intermediate and low temperature double-pipe heat exchanger, an electronic expansion valve and an outdoor heat exchanger; a hot water outlet of the high temperature double-pipe heat exchanger is connected with a hot water inlet of a radiant floor heating system; a hot water outlet of the radiant floor heating system is connected with a water inlet of a high temperature water tank; a water outlet of the high temperature water tank is connected with a backwater port of the low temperature double-pipe heat exchanger through a high temperature water-circulating pump; an outlet of an intermediate and low temperature water tank is connected with a water inlet of the intermediate and low temperature double-pipe heat exchanger through an intermediate and low temperature water-circulating pump; and a water inlet of the intermediate and low temperature water tank is connected with a water outlet of the intermediate and low temperature double-pipe heat exchanger. The CO2 high temperature heat pump sauna system has high heat efficiency, low cost, safe use and large water supply volume and can realize continuous water supply.

Description

technical field [0001] The present invention relates to a sauna system, more specifically, relates to a 2 High temperature heat pump system supplies CO to sauna system 2 High temperature heat pump sauna system. Background technique [0002] Sauna places require a lot of energy to prepare high temperature hot water and steam. At present, there are two types of sauna systems known, dry and wet, and the foreign market share is 42.7% for dry sauna systems and 57.3% for wet sauna systems. The dry sauna system requires the room temperature to be maintained above 45°C, and the human body sweats profusely to achieve the sauna effect. [0003] Currently, there are several ways to provide heat for dry sauna system floor and room air heating. Using electric heating water heating and electric heating air heating, regardless of heat loss, the highest efficiency is 100%. However, electric heating needs to consume a large amount of electric energy, and the cost per unit of hot water i...

AI Technical Summary

Problems solved by technology

The heating method combined with solar energy and heat storage system has high cost, low efficiency, and is limited by the weather

The use of ground source heat pump system, due to the lack of high-temperature heat pump working fluid, the cost of preparing high-temperature hot water is high, and the investment is large, so it is not suitable to use
