Description

technical field [0001] The invention relates to the field of energy equipment, in particular to a 500 / 600KW-5000 / 6000KW combined cooling and heating device. Background technique [0002] Current technology can only solve the unilateral problem of refrigeration or heating. Refrigeration equipment on the market, with freon as the refrigerant, cannot achieve rapid one-time large temperature difference cooling, and the cooling range is only 5 to 8 degrees. The equipment on the market that uses carbon dioxide as a refrigerant has a maximum power of less than 100KW and a low cooling capacity per unit time, which cannot meet large-scale cooling needs. [0003] For heating equipment on the market, Freon is used as the refrigerant, and the maximum heating temperature can only reach 55 degrees. The equipment on the market that uses carbon dioxide as a refrigerant has a maximum power of less than 100KW and a low heating capacity per unit time, which cannot meet large-scale heating nee...
